t5'1 G During water year 1984, the instantaneou's mlnlmum flow at Thomasville was less than the set rates On one occasion lin August and several occasions in September. When these situations occurred, the diversions into the project system were decreased or stopped, whichever was necessary to meet the bypass requirements. The Hunter Creek system, which drains into the Roaring Fork River, continued diverting water into Charles H. Boustead Tunnel. Exhibit 3 shows the instantaneous minim~m daily flows at the Thomasville River gaging station and the average daily minimum flow requirements. I . Project Diversions The water year 1984 outlook used a project diversion of 70,000 acre-feet for the most probable runoff condition. The February 1, March 1, April 1 and May 1 forecasts, based on Soi 1 Conservation Service snow course data, pro- jected diversions of 159,500 acre-feet, 64,100 acre-feet, 98,780 acre-feet, and 107,700 acre-feet, respectively. I The actual diversion from May through September was 107,630 acre-feet as measured at the outlet portal of the Cha~les H. Boustead Tunnel. The maxi- mum mean daily import through the Charles H. Boustead Tunnel was 942 ft3/s on June 15, 1984, with a maximum instantaneous peak of 963 ft3/s. A senior ca 11 was not made on the Co 1 orado River; therefore, no re 1 eases from Ruedi Reservoir were necessary to replace project diversions. The yearly total imports, the water used Ifor Twin Lakes Reservoir and Canal . Company exchange, and the accumu 1 ated imports to the Ark ansas River are shown on table 3. The 13 years of accumulated imports total 642,800 acre- I feet for an average of 49,450 acre-feet Per year. The discharge records for all diversions in water year 1984 are shown in appendix A. Measuring Devices During water year 1984, all gaging sta~ions that had not been previously verified by the Colorado Division of Water Resources Division 5 Engineer, were assumed to have acceptable rating tables for the measuring devices. I Twin Lakes Exchange On October 1, the Twin Lakes Reservoir and Canal Company began delivering water into the Roaring Fork River drainage in exchange for water in Twin Lakes, The exchange followed the operating criteria as shown'in appendix B. The total amount of the exchange at Twin 'Lakes was 1,879.51 acre-feet. Twin Lakes Reservoir and Canal Company's acco'unt in Twin Lakes was full most of the year and did not require imported wiater. Landsl ides caused two canal breaks on the west slope thereby restriqting imports. The monthly sunrnary is also shown in appendix B along with plots of the daily flows. 6 .
