Chairman I am Tom Harpool, Chairman of the Public Utility Board of the City of Denton. I have served on the B6qrd since it came into being. In 1948, the first assig-oment the Board, given was to assist in As- j lecting an engineering firm to help.develop a long range water plan. E With your permission, I should like to review some of the events, many of which you are aware, that hare; preceded the hearing today, Prior to 1.957, the City of Denton relied on underground sources for a water supply, however, with the steady growth of they City and a tlarrespohdi.ngl:y steady decline inthe capacity of wells to supply the 1 City, it became evident thatt~esCity must look to surface water to K supply its needs. On November. 24, 1948, the City filed application No. 1590 with the Board of Water Engineers for the State of Texas, On ,Tuna 17, 1954, a permit- to appropriate Public Maters of the State f # of texas was granted for the storage of 21,000 acre feet of'. water F , in the, Garza-Tittle Elm Reservoir, The perm;tt provides for`the di- vorston of not more than 11,000 acre feet of wager per annum, Later, it became evident that Denton's sharp of the safe yield i of the Garza-Little Elm Reservoir could, in year; of severe drought, fail to supply the needed water also water could possibly not be { I available for future growth. On November 19, 1.962, the City of Detiton entered into a contract with ~w. the City of Dallas that recognized certain safe yield figures. The contract made provisions for the City of Denton to purchase from the r j s ' Page 2 Statement of Tom Harpoul to Members of the Water Rights Commission s City of `Dallas additional water above Denton's saf"Ei yield tip to r an average annual rate of 13 MOD withdrawal by Denton from the Garza-Little Elm Reservoir, 1 The contract also recognized the need to construct Aubrey Reservoir, Denton agreed to participate in the construction casts of Aubrey Reservoir up to 26% of such costs. In return; the City of Denton would receive 26% of the waters made available by the construction. "The contract term is to the year 1980, or the comIJetion of Aubrey Reservoir, whichever comes first. ' In 1969, applications were filed with this body for the City of i Denton and the City of Dallas to be designated as 'Cooperating Local i Sponsors of the Aubrey Reservoir Project. Such designation was made f by this'Commission after a hearing held on June 4, 1969. In the fiscal. year 1970, there were no funds in the Administration's # budget for the Aubrey project. The cities of Denton and Dallas offered by resolutions to provide the $150,000 needed for advanced engineering and design. In the fiscal year 1974, the Administration's budget contained only $150,000 for tt:k project; however, thy: cities 4 of Renton'and Dallas reali.zod that at least $277,000 would be re- quired to keep the ro ect moving ona timely basis. Again, thp two ~ cities offered by resolutions to advance the necessary funds for the j project, i 1 In the past year and one-half, the cities of Denton and Dallas have negotiated water supply contracta on Aubrey Reservoir with the Corps of Engineers, U.S. Army, and we are now waiting Por final approval - - r ` page 3 Statement of Tom 1Carpool to Members (If the Water Rights Commission j of those contracts by the Corps The Corps has not negotiated Water Supply Contracts on Aubrey with any cities other than Denton and r Vallas, and it has never boen contemplated by any parties that s any other city or water district would.be involved.

Mr, Chairman and Members of the Commission; CIO My name is Roy Appleton, Jr. X am vice-president and general., manager of the Denton Record-Chronicle, a daily newspaper publish- ed in Denton,`Tefas. I also am Chairman of the Denton Chamber F of Commerce Water Resources Committee, First, Y },rant to express my thanks for the opportunity to speak to you today, 'on a subject that is very important to the citizens of Denton, The very fact that our Chamber of Commerce has 'a water resources committee is indicative of the concern and interest the people of Denton` have for the development of an adequate water supply. This strong concern began during the drought years of the mid- t t } fifties when Denton was beginning to grow and we depended on wells `yr for our total water supply. Garza-Little Elm Reservoir wai under construction and we had successfully negotiated fax water r rights there, However, the drought continued,'cxeattiig worry and doubt as to how many years it would take for the new reservoir + to fill and end our e;mergenoy. But, the rains came in May, 1957, and within little more than 48 hours, water was going over the ` spillway. We were 4old Dent~on's water supply was assured until i 1980. It would :have bee.i "easy for the people of Denton to relax and enjoy the benefits aJ the newr water supply at Garza-Little Elm. Fortunately, the majority did not, :They had seen over-pumped wells suck sand, over-worked pumps burn out, and storage tanks run dry with the knowledge that a fire would be a, major catastrophy. t Ow.

In 1940 Benton had no water problem and 11,192 citizens. Our population grew to 26,800 over the next 20 years according to th6 census in 1960, Suddenly, we were discovered, and we ballooned i.n to 40,000 in 1970. i Part of this-growth was due to three fine institutions "of the i e University, Texas 'Wo•man's Uni- State of Texas North Texas Stat ^versity, and the Denton State School for the mentally xetarded, Today our population has been estimated at 46,500, but we also serve 9,000 commuters at our two institutions of higher learning, over 55,000 people. And we have water problems, Our projections indicate a population of over 80,000 by 1990 and a`figure of 1.00,000 shortly after the turn of the century.

Dallas, stated they could not accept a permit with provisions relating J to customer dities. Chairman Carter stated that the Commission. ' was going to coridi.tion Dallas' permit, with provisions serving i . customer cities. Carter further stated that "If Dallas' position i f ' is the bottom line, we are wasting our time because Representative i Roberts will not support project on that basis. it looks like we have a dond project." Denton asked Carter why he thought the pro- ject was dead, and he answered "Well, if a major partner can't accept the permit wi.Lh conditions, it looks like the project is scrapped." )"rank Booth, on behalf of Denton, than stated that E, ' wanted to make an oral presentation concerning Denton's position and.would 0 o address himself to the unwillingness of Dallas to r s. participate with conditions,. The Commission told BooWV to proceed. Booth presented a 36 minute argument and staged that Denton's ; position was as follows i j (a) Disregarding prior rights, all parties, including J)allas, } { agreed that tho i.ncroased yield of the \ubresy pro j6ct was 81, 9 MGD1 (b) that nrnton needed and should be chanted a permit for 26% Of Clio 81.4 Mir; (c) that the staffs recommendation rogFardi.ng overdr aft;ing nhould bo fol.lowerl= j 0" L I of q (d) that Denton be allowed to Overdraft upon proof of an t alternate water supply source= M , (e) that the parties granted permits enter into an opera to tional agreement and if those parties can't; 'agree, the TOC write an agreement] a (f) that-the permits be granted, i.e. 74% to Dallas and 26% ` s~ to rieriton; j 1 (g) that Denton wants the project, that it should be started' im>ediately, that we trust the judgment and wisdom of the Commis- sion and will accept the permits with any condition t:ho commission desiredl (h) that if Dallas doesn't want to take their permit with conditions, then request the Texas Water Development Board to assume , { Dallas' 74% sharer d (i) t•.h4t Denton was ready to proceed with Dallas as a partner, or anyone else, as a partnerf ~ r (j) that Denton had requested 26% of the water because of a 1.462 agreement with Dallas, and if Dallas wanted out, then Menton r ~ I would desire more than 26% of Aubrey, lit the conclusion, Chairman Carter asked Booth how the Texas .Water'," Avel.opment Board could be brought into the project. Booth said that either Dallas could reject their permit or the Commission could deny it-, and Texas Water Development Board could be asked to r apply for 74% of the water. Booth went on to say that lie had some contact with the staff of ',Texas Watr.r Development Board and they seemed willing to participato and that it seemed that this was a way to resolve and solve the water situation for North Texas. i' Booth stated that tho Texas; Water Development Board was the proper ' t agency to develop the water r.asourccs x.11 North and Northeast Texas, + and this would got them started. He folt sure that TWDB cutsld con- tract to sell water to I,ewisvill3 (who had representatives prosant), ? a f ]Crisco, parmers Branch, Gainesville, North moxas Municipal Water` District, etc. ~ M2- ~J d'im Wilson representing Dallas stated that it would be im- practicable for TWD13 to COM in because Dallas owned the water die to its prior nights and the project would only yield 24 MGDI f and that the horizontal division in l,ewisiii.i3.c; presented problems, Booth said that we would take our chances on the prior rights and w thatt would be best to start adjudication proceedings on the lm Fork as soon as the permits were issued,' Ile stated that the y 1 stratification of x,ewisvil.le was not a problem because that had ) 1 been solved it other reservoirs ~ Dallas, through Wilson, stated they would accept a permit which:did not have conditions and requested the Commission to give ' them s ich a permit, Said that if Dallas `gets hurt on their rate Case, then they would have to split the blanket and no longer serve } those cities; and, in that case, Dallas would want the Elm ro:_k ~ reservoirs. 3 Carter resIended that "there are other people in North Texas' ~ }1, besides the City of Dallas and we have to lookout for those yolks in light of the limited sources of water", Ho stated that the ? fact "Dallas die. not want to take a permit with conditions chilled him".Commissioner Dorsey 1lardeman agreed that Dallas' permit should contain conditions that would give the customer cities the benefits of Aubrey. He disliked Dallas' attitude of suddenly ignoring those entitios. At this point, Graham (Ass't City Attorney of Dallas) stated that Dallas could not accept a permit with conditions when the FJ rate case was pending and they didn't know what h.he Commission ,r would do with that. Carter said he didn't think that the rate vase effected this'mattor and-that they should not hold up these t f permits until that care was conaludot". • 13ooth stated that. Denton j > was not involved in the :rate. matter and that wo should got an with this project. Carter agreed. Carter then said that it appoarod that Dallas wary unwilling to accopt a permit with conditions, and that: he waa "pronontly ..1 M , f disposed to denying Dallas' application and granting bent-on 's but he didn't know how to get other parties into the case", c Carter thon`asked Dallas if Dallas was trying to run this as h, a Dallas project. Wilson, chid not answer that question, but stated al that Dallas wanted :a permit as requested in their' position state- ,`i 4 . ;1 Mont, Cartet again asked if that meant Dallas wanted it as a Dallas .project. Dallas remained silent. t "hen Carter said, the reason x asked was that x understand that { ' Congressman Roberts is the sponsor of this project and he tells me r that he will not sponsor the project 'as a "Dajllas Projec t". lilt f thus appears that .if Dallas can't accept the permit other than on A i their conditions, they are out." A discussion took place as to what to do and the Commission thought that it would be best to study the situation and also to aS' make contact with the TWDB. They agreed to continue the hearing r!, until March 16 at 10300 A.M. I fL l Where does this leave Denton? In my opinion we are in great 'y shape, The TWRC has said that Denton will get 261. Dallas is on r; ~i the verge of getting }sicked out of this project and they really need to look at themselves, They have constantly wanted the whole pie and to eat it too, and that is backfiring on them. It now appears that Denton will have to wait to see if their partner is Dallas or TWDB. If it is the TWDB, there should not be any great delay. We have no preference and think Dallas should be in the project, but they are digging a grave for themselves and that is hurting' the project.. Thus, Denton may be better off with the !E TWDBI but it is Dallas' move.

Dallas also asks for diver ii lion cights'which will allow it i:o utilize its Lewisville i and Elm cork storage ef'f'ectively unbar its ove'rdraft opera. tion program. Dallas also asks that the applications of the appli._ Cants other than Dallas and Denton b^ denied and that no ' rights be granted other than to Dallas and Denton. It asks that no conditions be imposed on Dallas' permit-which seek two impose obligations on Dallas to se]:v other cities and t that no other unusual conditions be included in the permit. , Because of the diff eronces among the pi rtie., over the status of existing water rights, Dallas asks that ;:hcs Commission follow the precedent set in the recant Grapevine prvccodi,ng 2 n and not addxr,ss itself to the quostion of firm yiold, and it asks that no other provision be includ(!d in the permit which could be construed as an attempt to limit Dallas' existing ~ .

The yield computation of the Corps,of , Engineers admittedly ignores all water rights, The r',,:eese And Nivhols computation does not totally ignore prior rights, but it is based on assumptions as to 'Dallas' water riglats which Dallas contonds are insupporhable.

The basis for this policy is that: it would-be imprudent for a city' to divert substantially in excess of the amount of water which it can divert on a sut tained banii~ if theme ware to lv-.~ a repetition of the drought of record. A city Should riot become dependent upon a :Level of diversions from, at source of supply and then find that during a drought the water is not there. 'thus, the insertion of a, safe yield limitation in a permit, is not an end in itself but represents the applica-- tion 'oV a rational public policy. Dallas submits that the same public policy considerations which militato against a city divertiflzg and becoming dependent: upon divere ions ~ n eness of the safe yield, argue just as strongly against a C;Oy diverting, and be-voming dependant upon diversions of, a safo yield which is calculated on false as:>tunptions,. Actually, of course, there is no such thing ru:) a safe t• yJ.el.a which does not take prior ri nhts into account. Simi— Iarly, there is no such. thing as a safe yield, which assumes that diversions from downstream reservoirs will. be limited to the safe yield of; those reservoirs when (l) those is no legal restraint to Otte safe yield, (2) there it; substantial economic incentive to overdraft: the safe yield An such xeservoi.zs, and (3) such overdr.aftis may lie made safely because of other water supply soui:ccs. SQhen Denton asks this C'ommi.ssion for a permit with j i divcv,.ion rights equal to i.he firm yield calculated without concideratio.n of downstream rights, it is in ef:foct asking the: Commission to accord it the ric)11t to ovel:drilft the true irixm yield.

The other studies did not. This difference is not only significant, it'in crucial, and' to the extent that the author, suggests that Dallies' Lewis- Ville priority' does not extend to its diversion rights in excess of firm yield, there Is simply no basis for such a j conclusion. Although we believe that the preferable course would be to follow the Grapevine precedent and not address the safe yield question, Dallas has no particular objection to the GoMmi ssion' S granting permits on the Aubrey Project, w.i.th addi- tional diversion rights in. amo"nts equal to the increased yield as computed by the Corps of Engineers as long as it is s recognized that such a yield has no 'relation to what will happen in a real world drought and at, lorq as them is I not-)ling in the permit which purports to attribute reality to a yield which igno.ros downstream.,rights. i • 1 Mr. A.

P - subject, matter the' following represents my reaction to the evidence. y ` .1, Yield of Aubrey Project F The firm yield of the Aubrey Project (Aubrey Reservoir plus. Lewisville .f Reservoir e1114rgement) 'is totally dependent on the extent of existing doan- .i stream tinter rights and the priority of those iviter rfgl)ts. There is not s - 1 } significa~nt.disagreement among parties I;ivolved that the Aubrey Project f fRUnj 'inc"eases the'firm yield of-the existing Elm Fork systgar by about 81,4 mgd , ' 1 1 .1 T (91,200 acre-feet per year), i The computer simulations are merely a seMos of ,7;athematical cor,putations and the results are dependent only on the conditions and constra•lnts .established. The only s nificant difference betvreen all the yield studies • of the Aubrey Project is that the Dallas studies recognized full priority aver the proposed Aubrey project to the overdrafting of the existing Lake r~ I • Lewl$Ville. The other studies did not. . 2: Oa :rdrafting Overdrafting of a reservoir, or system of reservoirs, 'is th~~ diversion of y more water on an annual basis than the reservoir will continw: to sunily f through a repetition of the riost critical drou ht of record, i.e., the f -iri, E 'i yield, The practice of overdrafting of a portion of a supply syste;n can have s obvious operational and economic' advantages to a city; however, unless f t: Gt r 1 141 A 1. . 1101,10 to the Cornmtssion 2 February ll, 19715 t certain restraints are employed it can lead to di FfiGul ties for the ci ty. and, other water users. I feel the following general conclusions concerning 'drafting can be drawn. )ver c A. The total annual diversion by a city should not exceed the firin yield of n its total wager supply 'sYstenl-' B., When "overdrafting" of one portion of a supply system has occurred during tike critical drought then oversirafting some or, all of the rem- ining portionp of the supply, system must also occur in order to carry the system rr j' through t+,e critical, drought, k; , f C: lf, overdrafting of a portion of a grater supply system for municipal I purposes is to carry a prfori~ty o'er other uses junior in time the effect k will be to "tie up" a quantity of titer equal to several tries the ar;toun :E that can be used annually by tl,,e city, j, 3. Ope1_. atAeiitent The disagreements between applicants voiced during the hearing emphazises the necessity of an operating agreemant'between all parties having diversions rights in either the Aubrey or t et-lisvi l l e Reservoirs .

Newnam, Inc. It includes a brief review of the circuutstanges giving rise to the study and outlines the findings, conclusions, and recommendations j' resuiting from the study. a y SAY The results of the study may be summarized as follows: ;i i. The construction of Aubrey Reservoir is crucial to the question of accepting, new customer cities'. 2. Except for the Elm Pgrk Basin of the Trinity River, communities in the vicinity of Dallas 'reservoirs .A have service available from other wholesale sup- pliers established in the respective.tiver.basins.. 3, With Aubrey Reservoir, the Dallas system appears to havo adequate water supplies available for present and future customers in the Elm Pork Basin until the year 2000 and a rea&onable period beyond. } 4. Treated wator service might beat 'be limited to new customer cities adjacent to D411as or cities pres- ently served. 5. Rati water directly from the three reservoirs within I ' the Elm Fork Basin may be mado available to that portion of the Elm Pork Basin. surrounding the three ! reservoirs (Grapevine, Lewisville; and Aubrey). I The, rate methodologies that appear' appropriate for the various alto rna- j tives.are ;discussled later. f i 6 ; f f 4 1 t i RS'-2 f i BACKGROUND AND OBJECTIVES Voilowi,ng the drought of the 19508, the City of Dallas began a pro- gram of water resources; dev«lopment intended to asaure'a future supply adequate to meet watar requirements of the City and-suburban communities in, Dallas County.' The basic plan provided for , developmeint of water re . sourceAe in the 't'rinity' River, principally Grapevine Lake and Lewisville Lake, supplemented by water from Lake Tawakoni, Lake Ray 'Hubbard, and i 'Lake Palestine, Most recently, the City has made -a commitment to the construction of.Lake Aubvoy.. p tlistorically, the City's policy has been to extend water-.service to i "county towns," i,,e., communities in Dallas County. Later, thelpolicy f ~ J was broadened to'include -,communities in. the areas, impacted by the water supply re6ervoirs.

Recant water disputes and the need for long-range planning hsl}e prompted a thorough examination of ulternative• gui.ddlines to be used ilt extending water services.; The re-- port assists in defining the practical limits of the Dallas System and the circumstances under which Dallas could reasonably be expocted to pro- . ; ide water mtrvicea to new customer jurisdictions. I 1 - DR lZ ES-3 1 IDENTIFICATION OF A _PLANNING AREA r The study, involved a review and analysis, of watbr dimand and, sup- plies i.n an 18-coonty area of North 'T'exas, Tne arp.a was chosen because it embraces Dallas, its present -customer Jurisdictions,: and the !a?eas in the vicinity of the water supply reservoirs. Thiv area constitutes i the maximum geographic area within which the City of Dallas might reason-- i ably be requested to provide raw or treated water Services, In addition P S to Dallas County, the counties in the area are: Proximate Counties Ad anent to,Dallas Collin Denton Ellis Kaufman Rockwall Second-'Tier CAUnkies Cooke Pannin Grayson i Hunt Navarro Third- and Fourth-Tier Counties i Anderson Cherokee Henderson E trains , Smith z Van Eandt F Wood The third- and fourth-tier counties were included in the analysis because they are in the vici~tity of Take Palestine and Lake Tawakoni.

I Y The annual values applied to the energy expected from the proposed project are the values explained in Section 3.2 and listed on Table 3-3. s As in the evaluation of the Lewisville Project, the energy from the proposed . ' Ray Roberts Project was alternatively valued at the rate paid by the Denton l Municipal Water System for pumping energy. Y Table 3-11 summarises the results of the base case economic evaluation f which allowed bond financing and energy valuation at the rates listed on Table 3-3 for an October 1993 oru-line date for Gibbons Creek Unit 2 Of the four alternatives consid-ared,,the 1.3 megawatt installation lWars the ; - great eat economic incentive for development. The base `case economic evalua. tion indicates that the l.! megawatt facility would provide simple pay-back duritng the first year of operation, and that capital recovery woul3 be v- realized rive years later. The 30-year net present value is ostirit~ad~to be $4,084,b00 with the 1987 total investment of $2,557,000. With cea;t s r financing, the total construction cost of the hydroelectric development would be about $2,0570000. Detailed summaries of the economic svluatiour`of the proposed l.3 sagavatt facility are presented on Tables 3-12 through t` r 3-13. Those tabus su marise the economic ' performsoce of the proposed s' facility operating under various economic conditions. Figure 3-11 is a I plot: of the cv.>»ilative net present value for the first 13 years of operation.

The implementation of a pumped storage facility at Ray Roberts Data was assessed 1 to be impractical for two major reasons. The primary reason is that the I retention of water at the downstream end of the powerhouse d:r~pt, tube for subsequent pump back would require very extensive and expensive "oavation r t, .4~ of a lower reservoir. Additionally, the creation of a lower rbervoir would modify the hydrostatic conditions for which the Ray Roberts Dam hoe been s deEiped. That modification would likely result in a lengthy review and + revision of existing plans. The cost of excavation could be somewhat ^F 3-7 ~i tSi p, ski. St I V i ► ~ TABU 3-12.

The results of the feasibility study investigations performed to date support Vol the conclusions listed in the fallowing paragraphs. y 4.1 LMIMUJ ""CT Utilizing one of the existing 60-inch steel outlet pipes, 1.5 to 3.0 sngaxatts of hydroelectric generating capacity could be economically developed at Lewisville Dan. The facility would provide average anpual generation of between, 5.9 sW 74 million kilowatt-boors. Capital recovery of a total bonded iaivostment'of about $2,360,000 in 1983 would be raalizod,by 1995. 1 Simple pay-back would be achieved by 1987. Total annual s+tvings after " 30 years of operation would be about $25,400,,000. If financei from City, orating,funds, without a separate bond issue, the, total cost of the project would be about $10900,000 in 1963, and capital recovery would be realized by s 1993. If energy `enerated by the proposed facility is valued at the rate paid by the Dentop xMicipal water Systee for pumping energy, the cash i financed projer't would realize capital recovery by 1996 and show immediate , savingo in the first y*&r of operation. 44 1-.30h, the technical cud the financial fsasibility of developing the 14 k~. proposed project depend,upon.tbe ability to utilize the existing steal uutlat pipes; There does not appear to be any constraint against such a development. The construction and operation of a, powerhouse adjoiniag'tho ousting stitliag basin at Lewisville Dam. should be closely coordinate: with ' the Corps of Inginssrs. Eased on the conclusions described above, the following recomes"tions ;t are made: 1 ` 10 Apply fors prelisduary permit. 24 Initiate preliminary engineering' required to support an application j j t Ez f a for license.

Raquired sharing of benofits must be sessesed. t Results of the angineeriaij studies should be. carefully, monitored. If 4 ' nagative results are obtained, the effort should be halted. ' 4.2 MY 10DI RTS PROJECT If the planned 13-foot diameter outlet conduit can be utilised with only minor modifications, 1.1 to 2.3 megawatts of hydroelectric generating capacity could be economically incorporated into the development of 'Ray. Roberts Dsm. If,expencxve of time consuming modifications to the existing g design are raquirad, the implementation of <a hydroelectric facility at gay lobefts Dea may be impractical. -Utiliaing the planned outlet conduit, the proposed facility would, provide average annual generation of between 9.1 and 20,1 million kilowatt hours. Capital recovery of a total bonded investment of about 91,560,000 ti is 1967 would be realised by 199x, Simple ;pay-back would be achieved by CY 19x7. Total annual savings after 30'years 'of operation would,`be about $39,000,000 If financed from city opsrating funds; the total cost of tbo hydroelectric project would be about $2,0600 in 1987, and capital recovery ! would be realised by 1991.

STUDY SCOPE M METHODOLOGY The Cities of Dallas and Denton have had a long stand-, s ,i ing agreement to share in the financial support of the a construction of Aubrey Reservoir.' Construction of the project was originally planned by the Corps of Engi- neers for the late 1978's. Various circumstances have caused the project to be delayed. In recent years, different reports :have presented varying water yields and costs for Aubrey Reservoir, it is the intent of. this, study to review the various reports, to -analyze the, basic 'underlying financial and legal assumptions, ' and to develop a realistic estimate of the cost of water from alternative reservoirs in East Texas. It should he emphasized that this study will utilize' existing information and reports to a maximum while. focusing, on the areas of financial feasibility !and' financing alternatives. j As specified in the Request for Proposal, the sturdy f will investigate and analyze the following specific` areas: A. Aubrey Reservoir Cost Analysis two i 1AVFW 31 1. Safe Yield - A responsible "safe yield".' rating. Will be recommended for Aubrey. The primary basis for the rating gill be existing reports including those prepared by .the'U.S._ 1 4 corps of Engineers, Forrest and Cotton, Inc., , INC. .2 r r £k rf r r i . Freese a Nichols, Inc., and the "C"Itie$ ''of Dallas and Denton. In determznatioz~ of safe yield, prior water rights shall be fully recognized and the recent preliminary report p°p- - of the upper Trinity. Adjudication sha11 be the 'principal resource as to water rights. 2. Fodetal Project The Corps of Engineers estimates regarding. Construction costs, and construction schedules will, be xeviewed. With the Corps of Engineers as the financing and construction' agent, the normal 'project steps or phases and associated completion schedules will be identified. 3 Focal Sponsor y A` similar `analysis; will be , rude of the Cost and completion time:l if the cities 'or a separate local agency were to act as "the financing and construction agent. Under this analysis, the costs of flood control and recreational facilities planned by, the Corps of Engineers" will be separated. 4. stats Finanaing - LWfW` will investigate the availability and 'analyze the impact of using i ' - Ul Mate of.

East Texas River '$asin Reservoir Costs Analysis i The study team will review available engineering i h reports and identify one or more alternative water i supply reservoirs in East Texas. Comparative. costs estimates and completion times will be , developed for each alternative.: Using this data$ the cost 'of water delivered to Dallas 'and 'Defiton treatment plants will be projected utilising a model in which ener"' costs will be increased at a n 4 Y high, moderate and low rate of increase. . C. erational costs M The study will develop a cost schedule covering a both capital related costs and delivery 'cos", fox E raw water over a thirty (30) year period of time fro~a the reservoir completion date. A description of the methodology and assumption used.in prepar- k 1 i4g the cost schedule shall be included in the final report for each of the following three (3) alternatives: 1 l., A U.S. Corps of Engineers Aubrey Reservoir ~ Project rt to !f j INC. .4- 1 1 , i y-, 2 A locally sponsored Aubrey Water Supply Project ri 3. A reservoir constructed in the Sast Texas,' 3 River Basin. f Due to the number of alternatives requiring analysis and the major variables associated with each alterna- tive over time, LWFW intends to develop. a computer model' to simplify the analysis of alternatives. It is m~ t anticipated that this model can" also be 'utilized to simulate a variety of what if situations without involving a large amount of effort and cost. The LWFW study team will work closely with the Aubrey Steering Committee and meet on a regular basis to review study progress and findings as they are develo oped. A preliminary draft of the final report will be presented and reviewed with the steering committee i r prior to presentation to both Dallas and Denton. Following the preliminary draft report review, a final ? d~caft r'vport and presentation will be , made to both Cities. As a result of this presentation, a final ` report will be prepared and, submitted to both Cities along with a presentation to the Water Management ~f J Advisory council. le 4 r ~ yr n JLf INO.

I The Cities of Dallas and Denton have had a long stand j; ing agreement to share in the financial support of the } construction of.Aubrey Reservoir. Construction of the pro joist was originally planned by the Corps of Sngi- nears for the late 19'1.0s. Various circumstances have caused the project to be delayed, in recent years; 3 different reports have presented varying water yields and costs, for Aubrey Reservoir. 1t is the intent of review the various reports, to analyze this study to the basic underlying financial and legal assumptions, to develop a realistic estimate of the coat of and an alter frock alternative reservoirs in East Texas. it should be emphasized` that this study will utilize inforoation' and reports to a maxima While ~ existing ~ on the areas of financial' feasibility and focusing financing alternatives. 3 As specified in the Request for Proposal, the study i will investigate and k~nalyxe the followinq specific areas: l tj. r w .~s DYCYjM{Joir Cost Analysis } A.

STUDY APPROACE AND PLAN LWFW recognizes the value of the eontiOsrable work that has been done to date with respect to the feasibility E' of Aubrey Reservoir and views our most effective role t in this study as that of a catalyst. In the-role of a catalyst,. LWFW represents an independent economic specialist familiar with both Cities' needs and with the technical importance. of the 'engineering studies that have been doge to date. During, this study, LwrW will work with each organization that hat been directly i E involved with Aubrey Reservoir to update the previous studies, define.' financially feasible alternatives, and f help both Citi;as make c final decision regarding their 1. role, if any, in Aubrey Reservoir, { F In the course of this study, LWh'W intends to !work ' closely with both the Citier of Denton and Dallas' through the Aubre;( Steering Committee. In addition., LWOW will work closely with the following organixa ',ionsi URS/Forrest & Cotton, ~ c., Freese and Nicholas,; C,. S. Army Corps of Engineers, and First Southwest jr] S ~ 1 f ~lr Zt Financial Corporation. The Public Finance Department of j First National Bank of Dallas will also participate.'in ti { the study as a special resource in the area of finan- cial and economic analysis. s J it The remainder of this section describes the detailed j study plan for the Financial Feasibility Study of Aubrey Reservoir. The plan contains a summary of the major tasks to be performed during the study, as well { as a bar chart schedule illustrating the timing of each major task. I - A.

SAY ~AC1{CiROtJND NIV The .Financial Feasibility Study for Aubrey Reservoir was aoftissiohed. 'by 'the 'Cities ' of Dallas and lpenton, Texas, in OCtobeX , 1979r with. the following objectives: ` 1 To update cost estimates of Aubrey Reservoir, and to IR determine the estimated unit cost of water, 2 . To compare the cost of Aubrey water 'with the cost of ; { water from alternative reservoirs that could be con- strutted in East. Texas, , n 3: To evaluate alternative strategies; for sponsori g and =i constructing Aubrey Reservoir. xa, The concept of an Aubrey Reservoir 'originated in the 108 Corps of Engineers' plan for flood control along. the Elm ,F lay 9 Fork of the Trinity River. Throughout subsequent revisions x; to that plan and various among-range water supply studies, }fir completion of the Aubrey project has been antiripated. lender tiff ! the Corps of Engineers' Current, plan, Aubrey Lake 'would be constructed on the Elm Fork, a short distance' upstream from i , i the existing Lewisville Lake. The present.tbp of the`conser- vationlevel in Lewisville Lake would be permanently raised ,r by soVen (7,) feet. The Cities of Dallas and Denton have been granted water rights in the Aubrey project. These rights are << divided ;betWeezi.Dallas and Denton on a respective 74% - 26% basis, and Da11# s has the right to make the decision to build the reservoir. Dallas' projected water needs' can be 4tw!i4„, vt6, 4 r~4s .-P:~4Jl'[~` ~ kF r2 .1.Y.Y.{IJ Af Yn+S~{.~.r4 I,M 41`INt • supplied by existing r0 ervoirs for sore tine into' the future, but Denton has a need for additional 14 ez,supplies within the next ten (10) years. The Aubrey Steering Committee -was established to review ~ 01 study progress and provide input to the consultant. The steering"commi}tee consisted of: i Mr. Chris.Hartung, Chairman E3 t ( If City Manager, City of Denton, Texas ;s " a Mr. Bob Nelson Utilities, Director, City of Renton, Texas ILI • Ms. Camille Cates i Assistant to the City Manager, City of Dallas, Texas • Mr. Tom Taylor, Assistant Director,- Dallas; Water Utilities 3 Mr Clarence Warnst4fi Manager of Planning, Dallas Water Utilities The earlier Aubrey Reservoir studies and the organizations which have 3 performea then were a'valuable resource for this Two financial feasibility `study.'

A 04 I third finding was the, capital cost, financing terms, and operating and maintenance expenditures for •eaich project. AgreJment was' reached on Aubrey's benefit to the water supplY QYS14M in 'dejppndable "yield.

Dallas Water Utilities Department, whose operatianel ` Strategies affect the incremental b'enefit0 the Aubrey ILJLSroject. The primary question to be resolved 'athong theses parties was ..A I the system's incremental increase in dependable yield Aubrey Reservoir. Dependable yield is. the } 1 resulting from ~ , , ~aaximuat; dependable continuous withdza~ral ,"of water from,, a 4 reservoir `during a critical drought. Thu~a, dependable yieldf it afunction of water storage Capacity and the se~rerity o£ a probable ,drought, Aecords. over the' past fifty. years, are ured to. determine these probable drought conditions. since , one never knows whether a drought is imminent, water' is', not normally ;drawn'at a rate greater, than the safe yield. There fore, the dependable yield has been the traditional measure of increiriental benefit for water supply. DAIII s' multiple reservoir system allows' drafting in expects' of the 8eperidable 'yield from some lakes because any shoxtw i falls can be made up from other source. 2'he.,least expe'neive { water source is the Elm ` York' (Lakes Lewisville' an Grape vine) because the water flows to Dallas' treatment,plants.by } gravity. East Texas ''water (Lakes Rtiy Hubbard,` tawakoni, and F Palestine) has a higher 'direct cost because the water 'must I be pumped to Dallas;. To take maximum advantage of the least 1" i 1 - expensive sources of water, Dallas overdrafts , Lakes Lewis R i villa and Grapevine. This operating strategy results in a t, ! lower ncrt~mental benefit for Aubrey because it takes a ' .i p6ttion of Lake Lewisville's watershed area. { W o A` Y. a k sdy~i{i Y.wa` zN t', AFirts3.~23-, +n~7FNk ii y L W' V > ur. u-.,, e:f, :.e-,4.4!as LTeir F .a vn :.E V'AS.r,aXXPa •xY~•, K+s,,: e, x' b t ri th technical ` A cal workshop , way` he1.'d.. to brir q e teahni discute• Aulare) to s' the same table argaisixations to 'xagulted in an agreeaezi 4 . i) dependab a yield. xhis, workshop the Dallas water 'Utilities the assumptions to be used'' the incremental benefit to .the ' r I3epartmetlt in determining i + system dependable yield: of Aubrey under Dallas' operating Dallas operations strategy+ Subse tit computations using ' all the Interested pa;:ties and used ! `model' were reviewed by in this financial analysis. workshop included representatives The, finOcing/sponsorship Public ; the oration acid t} , of First southwest F'inAnciaL ''Corp in Dallas. artment of First, National Bank i Finance . ??bP Financing terms and instruments were•disousged based an the l;~ curxent'financial markets, In 'addition, alternative sources Because of the size , of financ,tnc this proect;were 'exnned, "Ile o£ the ra'se'rv'oir pro3ecits, crincern was expressed about the and f~lture other ° existing ` Cries,ility to caiply. with unic# al Watw, creation of a M p band covesisnts As a result, "L I any loce.l District might be considered for Financing Mo'ect.

Thus, the relevant reservoirs k 1 to compare with Aubrey are the reservoirs for which the transmission' facilities have been engineered.' These are Cooper Reservoir, sulphur Bluff I, and Sulphur Bluff II. In addition, the alternative of constructing Aubrey as a "Water Supply Only" reservoir' (rather than a Corps project) was evaluated. Aubrey Reservoir (Corps of Engineers) The Aubrey Reservoir project presently proposed by the Corps t of Engineers' includes raising the water conservation pool" t;, level of Lake Lewisville by seven (7) feet and transferring f some of Lewisvillets flood control storage to Aubrey. The water rights have been granted'to the Cities of Dallas and Denton, and are divided 74% and 26%0 respectively, The Corps f f... _ estite=3tes that oatober 1, 1979 construction costs total t $2301451,000, of which the local sponsoL's share is $159,659,200. The Cities' estimated annual reservoir operating and maintenance expense is $814,740. For projects started in the current Federal fiscal year, the y Corps of Engineers provides 7.210% financing with fifty (509) 1 years of equal payments, Payments on 52% of the water supply, cost and on the initial recreational facilities' begin when y the project's floodgates are closed. The remaining water supply cost is carried interest-free for up to ten (10) , 1 #i, { t P~VINCI .13w F'+ 1, r is Cj 11771 1 f ~ ears, and Y principal payments on the remaining portion can 3 be deferred until all of the water supply 'st'orage is used. g This analysis assumed that all of the water would be used i 71 after the tenth year, and that the future recreational development would take place at that point, b 12 Because of the corps of Engineers cost allocation formula, the cost of water from Aubrey was decreased by inclusion of I f' recreational facilities'in the project. All of the operating and.maintenance exp4nditures and none of the revenues asso- ciated with recreation were used to determine the cost of water in this evaluation, This is a conservative' approach;' as the actual treatment of these e.4~enditruea is up to the policy of each City, In addition, the Texas Department o£' t r x Parks and Wildlife; has expressed interest in operating some f of Aubrey's recreational facilities. This would signifi~ cantly lower the Cities' operating and maintenance, I expenditures from those used in this evaluation, t This study assumed that Aubrey would become operational in t 1990, and that water could be drawn from the hake aft ~ er ~ 1995. The Dallas operating model found that the incremental r I increase in dependable yield resulting from Aubrey is 73' J 1NGD, and that average use of the projects'' water will be ' 40.4 Wbo Because Aubrey water flows to Lake Lewisville by gravity- no tratxsm ssion or power cost is associated with i, this reservoir. z, I^rtNC. -14- F •1, 40 i 1 r Aubrey Reservoir ;Lpoal/Water Supply Only) ' An alte,knative ~ x to the Corps of Engineers' plan is to con- struct Aubrey as a "water Supply only" 1 project.

They and other analysts expect that the 1 rate of increase in energy costs will exceed the general inflation rate until the price,of fossil fuels reaches the level of alternative energy sources. At that point, the a ( energy inflation rate will become equal to the general ' inflation rate. This analysis has assumed that energy infla- tion~',will be 25% greater than general inflation through rk 1995, and equal to general inflation thereafter. In other words, during the next fifteen years, if general inflation is 4.;'Iinergy cost inflation will be 10% (i . e . , 8% `X 1.25) ¢ of the e/eneral inflation rato. f Typically, the cost estimate of a construction project may is y be. viewed as an "optimistic" assumption.' The capital costa t} of all ,these reservoirs will be affected by the fact that P$ North d'entral Texas is currently experiencing a higher rate JF of inflation than the J. S. average. Dallas area inflation I~ is particulai,ly high in real estate and construction. These factors are considereu in the "expected" case in which the ,i projectls construction costs exceed their estimates by 25%. The "pessimistic" case is that capital cost estimates will • be exceeded by 50%. The model e;-plied these assumptions to E' the October 1, 1979, capital cost estimates which were further increased by the assumed inflation rates to the a mid-point of the construction period. a,- f ! } ReMilts of Financial Analysis i A computer program was `developed to calculate the annual . cost of water` for each proposed reservoir. A sumrr.ary sheet for each set of assumptions shows the cumulative present value unit cost of water for each project. Complete results i , of this-program at all sets of assumptions are presented in ` i Appendix B, The following explanation and figures are based f upon the "expected" economic' assumptions of a 25% capital cost overrun and general inflation at 87, through 19951 and s` i 5% thereafter. ; Two (2) typical patterns of expenditures over time are shown ; E in Figures 3 and 4. For a Carps of Engineers project (Figure I J 3), debt service on approximately'half'the cost will begin J in 1990,; and continue for fifty (50) years, Debt service on i the remainder will begin ten (10) years later,' ending in 2050. Operating and maintenance expenditures increase' '6 } because of the expected rate of inflation. After 2050, j operating and maintenance will be the only expenditures. k Figure 4 illustrates the expenditures for sulphur Bluff 1 and ii, a locally financed project with a transmission facility. The debt repayment on the reservoir is compressed into thirty (30) years, starting in 1995. The transmission faoil-6ty is financed for thirty (30)`yearz, beginning in j 2000.

E The. two Aubrey options obviously' have the. lowest cost of j.. water, but the annual unit cost of water does not clarify j i 3 ` which of the two is better. i. ` The results of the cumulative present value analysis show as proposed by the Corps of Eng" that Aubrey'iteservoir, has the lowest unit cost of water `for the expected nears,.

Although the Aubrey Project would provide a large acreage of land .,ant' water' for f;. recreational `purposes, there will be many times when the shoreline Areas will ba aesthetically undesirable for recreational use. A' dual reservoir system such as the AubreyLswWlle system can be operated most effectivoly by maintaining a IoW water furface in the downstream reservoir (Lewisville Lakes so that, in the event 'of heavy rain's on the watershed, runoff can, be capturod rather than 1~~st through spilling from the downstream reservoir. This type of operation would 'most likely degrade the value of recreational x facilities at Lewisville Lake and would'make the reservoir much less attractive aesthetically. . At the same time, frequent releases would necessarily be made from Aubrey Lake to b + insure a continuing supply .at Lewisville Lake, The result Would be subaahtiaC variation ~r xn of the Water surface in Aubrey Lake, with deleterious effects on the recreational and + f aesthetle characteristics of Aubrey, 11, s Energy considerations would appear to favor construction of the Aubrey Project, because „ the supply from Aubrey Lake can LO transported to treatment facilities without pumping, However, from comparison of unit costs (assum€ V a 63;6 MGD yield from'Aubrio,: it was found to be less eXpensive at present day, priced to Pump WOW ftbm a.:ourra in the Sulphur River 6asir to the Elm Fork thin to build the Aubrey Project and utilise gravity flow, in order fat the unit cost of water from Aubrey end Sulphur fluff fieservoir ' " to be comparable, assuming capital costs to remain u'ncha'nged, the colt.of pointer would have to increase' to 0.2 times the present rate of 2,2 cents per' kilowatt hour, On the other hand, If the capital costs of the two projects were to increase by 60 percent by the time they were constructed, power costs would have to more than quadruple (multiplier of 4.8) to 10.6 cents per kilowatt hour in order for tho unit costd• of water Y to be comparable.

INTRODUCTION ' 2.01 DENtRAL History of Aubrey Project, The concept of Aubrey Project originated as part of a' 1939 j Corps of Engineers plan for control 'of floods In the Elm Fork Basin. The plan also recommehded construction of Grapevine and Little Elm Reservoirs, and modification of I the existing Lake' Dallas. Construction of the Elm Fork projects was authorized by Cor►jess by the River and Harbor Act of, 1945, ,IN If j Subsequent studies by the (;orps revealed that a single reservoir near Lewisville Would i be more: effective than 'the previously conceived Aubrey, Little Elm and Gana projects,-. ~ 'thus, a modified version 'bf the 1938, plan was derived, and Garza Little Elm (now f pleted in 1954. ` lake. Lewisville). was cf'm. The Dallas Water Survey Committee, appointed .1n 1853 and chaired by' the late W. G, Volimet', was charged with the ,ask of studying; long-rariga water problems, of the city } s of DaI 6s,, Working in oonjunotidn with I'Wre,t and Colton, Inc,; file committee developed a comprehensive plan for staged construction . of n3servo{rs and other facilities to most projected needs to the` year 2000: The adapted plan provided for development of ' Tawakortl, Fo~heY(Ray Hubbard); Aubrey and Roanoke-Raservoirsand,addre:sed poble constnuction'of the Blackburnro~ing l~eservoir'(novv Lake Palestine), Tice AUkrey project 4 I :I r, proposed to 'th~' Vollmer Study, was Intended prlmarily for water supplV punx,., ,but the project also ,Included'the' aoricept of provldIaq 239,000 acre feet off" control storepe' .

The rights listed above authorize the appropriation from Lewisville Lake in amounts far greater than the flH yield ,of the lake, Dallas can safely divert more than the firm yield 'it I without Jeopardizing the Integrity of Its supply, 'since it has backup supply available in other rdservolrs, namely, Lakes Tawakortl, Ray Hubbard and Grapevine.

Most importantly, the; operation permits maximum utilization of the gravity supply available from the Elm Fork Watershed, This minimizes the need for pumping supplies a and results In maximum energy conservation while reducing a had from. other waters r,{ k power, Furthermore, this mode of operation permits more effective use ' eupenditum for of flood waters which would otherwise be passed on "downstream.. f 3 At the Texas Water Rights Commission hearing on the Aubrey Project p~rrnit applieationa, r Dallas demonstrated that, It the City exercised Its rights in Lewisville Lake up to the amount of Dallas'° estimated year. 2000 needs of 282 MGD from the Elm Fork, and If Denton exercised Its full pppropriative rights In the these diversions would require the entire t flow of the Mm Fork not only during dro~ight perlods,' but during many other years j as well, and that the only water available for appropriation for the Aubrey Project would 4 r be a portion of the major floods which occur only Infrequently, Thus, under these conditions the increase in yield due to the Aubrey Project would be only 21,8 MGD. The water permits granted for the Aubrey Project divide the impoundment anti diversion rights between Dallas and Denton on a 7496 - 2696 basis, t espectlveiy, and authorize annual d;yersic>ns equal to the water conservation storage capacity.

The amount Of runoff, available willr' in turn, be affected by the amount of draft being ptac, 0J on f the Bum Fork Watershed. Assuming the condit(olts of the Dallas reservoir Paragraph 3.04, whereiri'yleld of the Aubrey system operation rrwnttoned' in Project .was computed ,to be 63.6 INC3D, ' and using long term aver age values of available runoff and net evaporation foss, the filling time of the Aubrey Project Would be about 14.5 years, on the swap , storing only those irtffows surplus to the needs of the Lewisville Lake operation. Unddr extremes of evaliabte runoff for the 51 ~ • year period of study from 1920 through 1970, tho time of filling wukf be as short as 2 years or as long 23 years, These filling times are all based on, the essumptton E that no demand Would be placed on the Aubrey Project stored waters during initial filling, the filling time would of course be lengthened' if withdrawals Were made from Aubrey I N storage Mom Lake Stage In Aubrey Lake, the conservation storage capacity In Aubrey Rake was increased.to nearly awwo acra•feat In'the most recent design by the Corps of Engineers In order to obtain the most yield oractlcal from the project, The storage is i more than four thtes is great "es 'tho average annual watershed runoff, and `the take cannot t be opectod to stay full much of the time.
