Partner-Administration NORMAN W. HANER Partner-Engineering _j f-• North Paclftc Consultants 220 S. W. Alder Street ~rtland 4, Oregon Gentlemen: Port I and, Oregon Ju I y 1 5, t 958 l hav.e rev tawed your reservol r storage studies for the Cooper lake Project, Alaska, and concur wfth your findings. Yours very truly, BET:ee RESERVOIR STORAGE STUDY Actual records of discharge are available for the outlet of Cooper Lake for the period of September 1949 to the present date. Records of rainfall are available for the period of 1909 to the present with the exception of 1912, 1917, 1910 and 1925 -1929 inclusive. However, Seward rainfall was estimated for all the missing years except 1912 from the record at a nearby station at Latouche. \~ith these rainfall records and the actual discharge records,a factor was developed and a hydrograph computed for the period 1913 to 1949. After the Cooper Creek hydrograph was completed, a hydrograph for Cooper, Ptarmigan and Stetson Creeks was computed by assuming that runoff would be proportional to the drainage area. Water yield was adjusted in accordance with condition 2 as discussed in the attached 11 Study of Diversion from Stetson Creek". A mass diagram was then p-repared for the years 1913 to 1957. This mass diagram is plotted on Chart 4 using 90,000 acre feet as the normal annual runoff. The deviation from this normal is then the plotted graph. A study of this mass diagram indicates that the critical runoff period is th~t from 1913 to 1921 and 1950 to 1957. The Chart also indi- cates that the mean draft of 115 cfs proposed could be obtained with a live storage capacity of 80,000 acre feet. The computations are based on the assumption that the runoff for 1950 will be no greater than that for 1957. Present indications are that this will be the case. In order to obtain this capacity with a maximum pool elevation of 1200, drawdown to elevation 1166 would be required. This drawdown is entirely feasible with the proposed design. Cost analyses also indicate that, with the - 1 - \AI <n;;:J ,.,. (!) c Ill C.Cb -<""' < 0 ""'; ....,. ' 0' ' • .. ... toad factor proposed, the reconmended installation and the pool elevation 1200 are approximately correct. A further study was made to detennine the value of additional storage • In making this study, the powerhouse, penstock, conduit and tunnel were assumed ·to remain as recon'11181'ided. Increased cost would be due to increased height of d•, increased clearing and Increased height of intake structure and surge tank. Using the mass diagram on Chart 4, required I iva storage for increases in power draft ware datennined. The required pool elevation was then determined from the storage area curve. The value of this increased flow was computed using 8 mills per~ for the value of power. To the capitalized value of this Increased flow~~ added.$7,500 per foot for increases in net head. These values were then plotted on Chart 6 ~ere a curve of dam costs were previously plotted. The slope of these two curves are then ~ared. 'The point wnere these curves become parallel,· poo I e J evat ion 121 0, indicates the maxi num ecanomi c height to ...., i ch the dam can be canst ructed. It Is recommended that the maximum pool elevation be 1210 feet mean sea leva 1. ' DrawdownwiJJ be limited to elevation 1166 feet. Thf s provides for an active storage of 108,000 acre feet. With this additional storage, regulation is effected over a greater·number of years, and the developed hydrograpn shows that the five years used in the DPR were extremely conservative. With this additional regulation, a higher annual yield Is available for power purposes. 'The intaka structure wi I 1 be designed ror a maxinum ice thick- ness of fi¥e feet. This design is considered to be very conservative since such a thickness would only occur if the powerplant were shut down for a conside~able pe~iod du~lng the coldest pa~t of the yea~. Expe~ience indi• eates the.outlets of deep Jakes sueh as this one a~o always iea f~ee during the eoldest pe~iods. Since the quantity of wate~ d~awn th~ough the outlet structure du~ing the winter months would be mueh greate~ than the outlet flow under natu~al conditions, the area a~ound this structure sh~uld be quite fee f~ee while the powerplant is operating. 51\JDY OF DIVERS I ON FROM STETSON CREEK The studies were prepared fo~ three conditions as fol tows: 1. Utilizing dive~sion of all waters of Stetson C~eek to a maxinum of 70 cfs for the months Hay th~ugh Novente~ .only and allowing all wate~s to pass the divei"Sion structure from December th~ugh Apri 1. 2. Diverting only that wate~ in Stetson C~eek to a maximum of 70 cfs ~ich would leave a ~esidual flow In Coope~ Creek at 0.7 of a mile f~m its mouth as proposed by u.s • .' Fish and Wfld.Jife Se~viea !I (Alaska) as·:tiollows: Hay June July August September October November Deeember through April 30 cfs 80 cfs- 70 cfs 40 cfs 35 cfs 35 cfs 25 cfs no divers i·on ll These flows were essentially incorporated by the u. s. Fede~al Power Conmission in its release of the construction permit fo~ the Cooper Lake hyd~Ject~ic p~ojeet on July 3, 1953. lt may be presumed that another year's study by fisheries interests will result in a somewhat lowe~ requirement for minimum flows. In any event, FPC eonside~s the stated flows as a top limit. - 3 - i I ·-1 !· / .:. . . .. ~ 3. Diverting only that water in Stetson Creek to a maximum of.70 cfs which would leave a residual flow in Cooper Creek at 0.7 of a mile above its mouth as proposed by Chugach Electric Assoc •. ll as follows: May through October November Oec:embe r through Apr i 1 30 cfs 20 cfs no diversion The results of these studies are shown in ·the attached charts 2, 3, 4, and S, wnich show a mean annual flow of J4o.l cfs, 130.0 cfs, and 134.5 cfs for each of the studies numbered above. Computation sheets are attached. The drainage areas used in these computations are as follows: Cooper Creek 0.7 mile above mouth Cooper Creek at dams i te Stetson Creek Ptarmigan Creek I 48.5 sq. mites 31.17 sq. miles 9.31 sq. miles 2.18 sq. mites ~ . "' The flows developed herein do not make allowance for loss due. to seepage and increased evaporation over the amount evaporating f~ the existing lake. In the OPR, thi$ value was taken at 5.75 cfs continuous. Assuming that this value would be increased to possibly 6 or 6-J/2 cfs, the resultant continuous flows available are materially greater than con- sidered in the DPR. ' The available flows as developed, and utilizing an active storage of 108,000 acre feet, shows that slightly more power can be obtained from the yield of the Cooper lake basin plus Ptarmigan Creek than was used in the OPR for Cooper Lake, Ptarmigan Creek and estimated diver- sian fnom Stetson Creek. Therefore, it appears that the feasibility is slightly better without Stetson Creek than was developed in the DPR and l/ These flows were suggested by Chugach Electric to the u. s. Federal Power Commission prior to the recommendations of u.s. Fish and Wild• 1 ife Service. - 4 - subsequent studies in connection with the application for funds. The additional yield 'll'hich can be obtained from Stetson C'reek will materially improve the feasibility even though project operations will be required to maintain the minimum flaws recommended by the U.S. Fish and Wildlife Service (Alaska) and the u.s. Federal Power Commission. Referring to the minimum flows recommended by u.s. Fish and Wild- life Service and the u.s. Federal Power Commission, and referring to the copies of the calculation to determine the available yield from Stetson Creek, it can be seen under present conditions, accepting the fact that no flow would be available from Cooper Lake, there are periods during 'll'hic:h time the minimum flows required wautd not be. available!:!.!!!. though .!J2. diversion. were ~de from Stetson Creek. It would appear desirable therefore, after-another year• s study is made of flows required for the I preservation of fisheries on lower Cooper Creek, including the effects of its channelization, to sc:aie those mininum flows to a nr:Jre realistic: level. Material increases in the project•s revenues, over and· above feasibility, \tl!OUid result. -s- I t- ~ < Q ~--~ \,...)\.1.1 IJ..Jo.. J 8 Q \J 0::! ~ a.. 0 Cw u.. J.., i ~ < <t w (!It ..-J ....
