The monthly streamflow series were derived using the streamflow data of the Susitna River at Gold Creek and at Cantwell. The resulting series averages 7955 and 9056 cubic feet per second (cfs) respectively at Watana and Devil Canyon. The 7-day series were based on data at Gold Creek Station. The resulting series averages 8201 and 9198 cfs respectively at Watana and Devil Canyon. R&K Counsultants. Incorporated (R&K) and Dr. W.D. Harrison of the University of Alaska, have investigated probable monthly contribution of glaciers to the recorded streamflow at Gold Creek for the months of June through Septem- ber. Based on results of the investigation, five scenarios of monthly streamflows were constructed for Watana based on different assumptions of glacier contributions. 11 References listed at the end of text. -1- 3.0 SCOPI or 1BI stUDY The major work items of the present study include: 1.

Comments and necessary improvements to these time series also are discussed. 4 .1 STREAMFLOW EXTENSION ACRES selected a co111110n base period of 30 years (1950 to 1979) for the monthly streamflow series and used the available str .. ,unflow data at eight stream gaging stations (Exhibit l) to es tiaate missing 1110nthly flows at eac:, station. An in-house computer program, based on the program FILLIN devel- oped by the Texas Water Development Board (2) was used in estimating the data. The periods for which observed d.ata were av,'lilable and the periods for which the data were estillldted are shown on Exhibit 1. -2- The FILLIN coaputer progra~~ is based on a 11Ulti-site regression technique which analyzes .onthly streaaflow series and estiaate .U.ssing data. The progra11 evaluates statistical para.etera ( ~~eans, standard deviations, lag- one auto-correlation coefficients and lllllti-site spatial correlation coef- ficients) and estiaate .U.asing data in which the statistical para.eters are preserved. The priaary objective of ACRES' analysis was to generate 30 years of IDOnthly atreaaflow sequence at Cantwell stream gaging station. These data were used with those at Gold Creek streaa gaging station to estiaate flovs at the two daa sites. A coapariaon of the statistical pera~~eters of recorded and filled-in data series at Cantwell, provided by ACRES(l) indicate nearly the saae statistical par8111eters in both cases. Therefore, the 3Q-year streaar flow series at Cantwell is considered acceptable. The 1110nthly streallflows at Cantwell and at Gold Creek are given in Tables 5 and 6. 4.2 STREAMFLOW TRANSPOSITION ACRES derived the IBOnthly streamflow series at the two dam sites using the following relationships: '\ QDc • 0.827 (QG - Q ) c + Qc Qw -0.515 (QG -Qc) + Qc in which QDc .. Monthly flow at Devil Canyon; Qw • Monthly flow at Watana; QG • Monthly flow at Gold Creek; Qc • Monthly flow at Cantwell The coefficient of 0.827 is the rati.o of the drainage areas between Cantwell and Devil Canyon to that between Cantwell and Gold Creek. Similarly, the coefficient of 0.515 is the ratio of the drainage areas between Cantwell and Watana to that between Cantwell and Gold Creek. -3- ACRES computed the 7-day streamflow series at each site by adjusting the 7- day flows at Gold Creek with the ratio between the drainage areas upstream of the site and that upstream of Gold Creek. The flows at Cantwell were not used because the 7-day flows were not generated at Cantwell for the missing period of record at the station. Since ACRES used different methods to generate the monthly and 7-day stream- flow series, a check was made to evaluate the differences in the streamflow data if the monthly flows also were generated by using the method adopted for the 7-day flows. For a few selected years, the flows transposed by this method are about 3 to 10 percent higher than those generated by using equations I and II. It would be better if the 7-day streamflow series is also generated by the same method used to generate the monthly streamflow series. However, that will require the estimation of missing 7-day flows at Cantwell which will involve considerable effort without assurance of significantly reducing the differ- ences between the two series. The accuracy of streamflow records at the two gaging stations is fair to good with a probable error of +5 to +10 percent (3). Since the difference in the monthly and 7-day flow series are within this accuracy, both series are considered acceptable for reservoir operation studies. Transposition of flows by drainage area ratios is acceptable if there is no significant variation in seasonal or annual precipitation amounts over the two areas. This was examined by using mean annual precipitation map (Exhibit 2) developed by the Soils Conservation Service (4). The mean-annu- al precipitation (MAP) upstream of Watana and Devil are about 37.4 and 36.8 inches, respectively. The MAP upstream of Gold Creek is about 36.6 inches. The differences in the MAP upstream of the three locations are insigni- ficant. Therefore, no adjustments to the estimated streamflows for dif- ference in precipitation are required. -4- 4.3 ADJUSTMENT TO 1969 STREAMFLOW For the period from 1950 to 1979, the lowest mean annual flow occurred in 1969. ACRES made a frequency analysis of mean annual flows at Gold Creek and estimated a return period of more than 1,000 years for the 1969 (water year) flows. Since ACRES accepted a return period of 30 years for the selection of allowable reservoir drawdown and firm energy, the observed 1969 mean annual flow of ~.561 cubic feet per second (cfs) was replaced by a 3Q- year low flow esti.mated to be about 7,200 cfs. The monthly flows were then derived using this value and the ratios of long term mean monthly and annual flows. The recorded monthly streaaflows at Cantwell also were replaced by a 30-year low flow. The resulting 1969 streaaflows at Gold Creek and Cantwell were used to compute the corresponding flows at the two dam sites. The use of higher stream£ lows for the year 1969 is inappropriate because this will alter the sample distribution of historical data which, in turn, will cause difficulties in properly evaluating the probabilities of firm energy and water shortages. Furthermore, in the frequency analysis made by ACRES, the 1969 data was treated as an outlier having a return period of over 1,000 years. Such an assessment ls highly uncertain considering the short period (30 years) of records. Therefore, the 1969 streamflow included in Tables 1 through 4 are those based on observed records. 5.0 GLACIER OORTRIBDTIOR Dr. W.O. Harrison and R&M have made a preliminary study of glacier contribu- tions to streamflows at Gold Creek. The study resulted in five scenarios of streamflows at Gold Creek each corresponding to one of the following assump- tions. 1. Glaciers were assumed to have net zero loss during the 1949-80 period, but there were annual variations in the waste. Annual contributions during the period were estimated using the Tangborn -5- • • • • • • • • • 2. 3. 4 • runoff-precipitation model (4, 5) and used to adjust the recorded flows. The resulting flow series represents the condition of zero contributions from the glaciers in each year • Glacien were assumed to have wasted 25 meters (82 feet) during the 1949-80 period. Annual contributions were estimated using the Tangborn model, and used to adjust the recorded flows • Glaciers were assumed to have wasted 45 meters ( 148 feet) during the 1949-80 period. Annual contribution were estimated using the Tangborn model, and used to adjust the recorded flows. Glaciers were assumed to have wasted 25 meters (82 feet) during the 1949-1980 period. Annual contributions were estimated using the 'I'angborn model, and used to adjust the flow series resulting from Case 1. 5. Glaciers were assumed to have wasted 45 meters (148 feet) during the 1949-1980 period. Annual contributions were estimated using the Tangborn model, and used to adjust the flow series resulting from Case 1. The Tangborn model (4,5) computes annual glacier balances by relating measured precipitation amounts and annual mass balance of glacier with differences in runoff between a glacierized basin and a nearby non-glacier- ized basin. R&M computed the model parameter using data for one glacierized basin, Phelan Creek draining Gulkana Glacier, and two non-glacierized basins listed below: -6- --• Non-glacierized Basin Index Precipitation Station Ship Creek Talkeetna Ship Creek Gulkana Caribou Creek Talkeetn.a Caribou Creek Gulkana The resulting estimate of annual contribution by the glaciers was distrib- uted in the 1110nths of June through September based on average 1110nthly temperatures at Talkeetna and a base temperature of 43°F for thawing degree days, allowing for a lapse rate of about 3°F per 1000 feet between Talkeetna and the glaciers. The differences in 1110nthly contributions between Cases 1 and 2 (scenario 4) and Cases 1 and 3 (scenario 5) for the period 19.50-79 are given in Table 8. The values in this tablt! can be subtracted from those in Table 1 to obtain adjusted streamflows for Watana refleting respectively, 25 and 45 me t ers (82 and 148 feet) of net glaciers wastes during the 1949-80 period. The estimate of 45 meters ( 148 feet) of glaciers waste during the 1949-80 period was based on two sets of photos taken in 1949 and 1980. Since the photos were taken without vertical and horizontal controls and the analysis wa s made only for East Fork Glacier which constitutes only five percent of glaciers in the basin, the estimate of 45-meters (148 feet) waste is highly speculative and questionable. In view of the uncertainty in the estimate, R&M made another assumption of 25-meter (82 feet) waste in the computation. A brief water balance analysis based on available mean annual isohyetal maps of the basin and streamflows records at the Susitna River near Denali and the Maclaren River near Paxson !ndicated that the glacier wastes during the 19 49-80 period is mo r e likely to be in the order of 22 meters (72 feet). Currently, pertinent data a re not available to verify the estimated historic waste or mass balance of the Susitna glaciers. Regardless of how much effort is made to reconstitute historical waste s of the glaciers, the -7- • • • resulting estimates would be of high uncertainty. However, in the absence of any better information, the glacier contributions as estimated by R&M and Dr. Harrison (Table 8) could be used through a sensitivity analysis to eval- uate their effects on power production. The streamflow series at Watan.a adjusted for these constributions are given in Table 9. However, the adjusted series shown in this table represent no contribution or at least great reduction in contribution from the glaciers, and there is no estab- lished evidence that such a situation will occur when the Susitna project is placed in operation. 6.o usnvou IVAPOIA1'IOI Net reservoir evaporation from the Watana and Devil Canyon ~:eservoirs are estimated to be negligible. The procedures used in the estimation are dis- cussed below. Pan evaporation data near the Susitna River basin are available at McKinley Park, elevation 2,070 feet above mean sea level (ft,msl) and Matanuska Agricultural Experiment Station, elevation 150 ft,msl. These data are given in Tables 10 and 11, respectively. Based on normal pool elevation of the Watana reservoir (about 2,185 ft,msl) and a comparison of monthly temperatures at Watana and McKinley Park (Table 12), the pan evaporation data at McKinley Park is considered applicable for Watana. The mean monthly evaporations for June and July at this station are about 82 percent of those at Matanuska. Using this as an adjustment factor, the long term mean monthly pan evaporation, fop: Watana were computed as shown in Table !3 . R&M measured pan evaporation at Watana fro~ May 8 through August 31, 1981. rhe June , :.~ 0 u5h August evaporation was about 9.42 inches ( 1). The long te~:m evaporation for the corresponding period is 9.5 i~ches (Table 13). -8- Table 14 indicates sub-freezing temperatures of Watana for the 110nths of Octocber through April. Because of ice cover over the reservoir, evapora- tion during these months would be negligible. The mean annual pan evapora- tion is, therefore, about 14.7 inches (Table 13). Lake evaporation for the months of May through September was computed using a pan coefficient of 0.7 (see Table 13). This gives May through September lake evaporation of about 10.4 inches. This value is close to the R&M's esti~~.ate of 10 inches of reservoir evaporation at Watana ( 1). Precipitation data at Watana are available since May 1980 (Table 14). These data are too short to compute long-term mean precipitation and mean net reservoir evaporation. The mean annual precipitation at Watana was esti- mated to be about 30 inches from Exhibit 2. Monthly distribution of precipitation at Matanuska and McKinley Park are given in Table 15. The May through September precipitation is 63 and 67 percent of the annual precipitation. Other precipitation stations near the Susitna basin, also show percentages close to these values. Using McKinley percentages and 30 inches of annual precipitation at Watana, the monthly precipitation at Watana were estiuted as given in Table 13. Except for the month of May, the monthly precipitation amounts are signif- icantly higher than the estimated lake evaporation. Net evaporation from a reservoir can be estimated by the difference between evaporation from the reservoir surface and evapotranspiration from the same area prior to construction of the dam. A comparison of the estimated annual reservoir evaporation with annual evapotranspiration as represented by the difference between orecipitation and runoff (in depth of water) indicated that net reservoir evaporation loss for Watana would be in the order of one to two inches which represent a reduction of 4 to 8 cfs from the mean annual -9- --flow. This is quite negligible compared to the mean annual flow of about 8,000 cfs. Devil Canyon reservoir is located under the general climatic conditions (excepts at lower elevation). Therefore, net reservoir evaporation at this site also can be assumed negligible. -10- TABLES TABlE 1. ~lNlliLY STRFJ>.MF'lil'1 AT WAT.ANA (CFS} OCT NOV DEC JAN FEB HAR APR HAY JUN JUL AUG SEF' 1950 4719.9 2083.6 1168.9 815.1 641.7 569.1 680.1 8655.9 16432.1 19193.4 16913.6 7320.4 1951 3299.1 1107.3 906.2 808.o 673.0 619.9 1302.2 11649.8 18517.9 19786.6 16478.0 17205.5 1952 4592.9 2170.1 1501.0 1274.5 841.0 73'5.0 803.9 4216.5 25773.4 22110.9 17356.3 11571.0 1953 6285.7 2756.8 1281.2 818.9 611.7 670.7 1382.0 15037.2 21469.8 17355.3 16681.6 11513.5 195ft 4218.9 1599.6 1183.8 1087.8 803.1 638.2 942.6 11696.8 19476.7 16983.6 20420.6 9165.5 1955 3859.2 2051.1 1549.5 1388.3 1050.5 8 86.1 940.8 6718.1 24881.4 23787.9 23537.0 13447.8 1956 4102.3 1588.1 1038.6 816.9 754.8 694.4 718.3 12953.3 27171.8 25831.3 19153.4 13194.4 1957 4208.0 2276.6 1707.0 1373.0 1189.0 935.0 945.1 10176.2 25275.0 19948.9 17317.7 14841.1 }Q58 6034.9 2935.9 2258.5 1480.6 1041.7 973.5 1265.4 9957.8 22097.8 19752.7 18843.4 5978.7 1959 3668.0 1729.5 1115.1 1081.0 949.0 694.0 885.7 10140.6 18329.6 20493.1 23940.4 1246i .. 9 1960 5165.5 2213.5 1672·3 1400.4 1138.9 961.1 1069.9 13044.2 13233.4 19506.1 19323.1 16085 •. s 1961 6049.3 2327.8 1973.2 1779.9 1304.8 1331.0 1965.0 13637.9 22784.1 19839.8 19480.2 10146.2 1962 4637.6 2263.4 171,0,4 1608.9 1257.4 1176.8 1457.4 11333.5 36017.1 23443.7 19887.1 12746.2 1963 5560.1 2508,9 1708.9 1308.9 1184.7 883.6 776.6 15299.2 20663.4 28767.4 21011.4 10800.0 1964 5187.1 1789.1 1194.7 852.0 781.6 575.2 609.2 3578.8 42941.9 20092.9 14049.2 7524.2 1965 4759.4 2368.2 1070.3 863.0 772.7 807.3 1232.4 10966.0 21213.0 23235.9 17394.1 16225.6 1966 5221.2 1565.3 1203.6 1060.4 984.7 984.7 1338.4 7094.1 25939.6 16153.5 17390.9 9214.1 1967 3269,8 1202.2 1121.6 1102.2 1031.3 889.5 849.7 12555.5 24711.9 21987.3 26104.5 13672.9 1968 4019.0 • 1934.3 1704.2 1617.6 1560.4 1560.4 1576.7 12826.7 25704.0 22092.9 14147.5 7163.6 1969 3135.0 · 1354.9 753.9 619.2 . 607.5 686.0 1261.6 • 9313.7 ·13962.1 ,1-4843.5 7771.9 . 4260.0 1970 2403.1 1020.9 709.3 636.2 . 602.1 ' 624.1 986.4 ' 9536.4 '14399.0 ·18410.1' 16263.8 ' 7224.1 1971 3769,0 2496.4 1687.4 1097.1 777.4 717.1 813.7 2957.2 27612.8 21126.4 27446.6 12199.9 1972 4979.1 2587.0 1957.4 1670.9 1491.4 1366.0 1305.4 15973.1 27429.3 19920.3 17509.5 10955.7 1973 4301.2 1977.9 1246.5 1031.5 1000.2 873.9 914.1 7287.0 23959.3 16351.1 18016.7 9099,7 1974 3056.5 1354.7 931.6 786.4 689.9 627.3 871.9 12889,0 14790.6 15971.9 13523.7 9786.2 1975 3088.8 1474.4 1276.7 1215.9 1110.3 1041.4 1211.2 11672.2 26689.2 23430.4 15126.6 13075.3 1976 5679.1 1601.1 876.2 757.8 743.2 690.7 1059.8 8938.9 19994.0 17015.3 19393.5 5711.5 1977 2973.5 1926.7 1687.5 1348.7 1202.9 1110.8 1203.4 8569.4 31352.8 19707.3 16807.3 10613.1 1978 5793.9 2645.3 1979.7 1577.9 1267.7 1256.7 1408.4 11231.5 17277.2 18385.2 13412.1 7132.6 1.979 3773.9 1944.9 1312.6 1136.8 1055.~ 1101.2 1317.9 12369.3 22904.9 24911.7 16670.7 9096.7 1980 61.50 3525 2032 ]470 1233 1 l 77 14 04 lfll !·" :?3400 26740 18000 11000 1981 663 2 3044 1790 1858 1592 1262 1 ti 4 I ] ,'!
