<br />1815 <br /> <br />. <br /> <br />water year 1987. The District purchased 12,022.00 acre-feet of the <br />water made available to them. The District called for 15,940 acre-feet <br />of water during the year. The carryover Project water was also reduced <br />by 4,480 acre-feet of evaporat i on. By the end of September, the <br />District had 7,032.79 acre-feet of 1986-1987 water and 77,084.23 acre- <br />feet of carryover water. Of the 15,940 acre-feet of Project releases, <br />3,167 acre-feet was for municipal and industrial use. The Project <br />water released from Pueblo Reservoir is shown on exhibit 20. <br /> <br />K. Reservoir Storage Allocation Data <br /> <br />Table 9 presents the reservoir storage allocation data for the <br />Project's five reservoirs. <br /> <br />L. Reservoir Evaporation and Precipitation <br /> <br />Table 10 and Table 11 present the monthly average evaporation and <br />precipitation from the four weather stations in the Fryingpan-Arkansas <br />Project System. The daily water surface evaporation vs. computed using <br />the factors during periods when the evaporation pan is not in service <br />and the reservoir is not 100 percent ice covered. <br /> <br />M. Flood Control Benefits <br /> <br />During water year 1987, there were two occurrences in which Pueblo <br />Dam was used to control flow in the Arkansas River. The first <br />occurrence was from May 18-22 when the flow at the Avondale gage <br />exceeded 5,000 cubic feet per second and the State of Colorado requested <br />reduced flows from Pueblo Dam. At the same time high flows on the <br />Huerfano Creek created possible dam failure problems on Cucharas Dam. <br />The flows from Pueblo Dam were continued at the lower rate until eva- <br />cuation of water from behind Cucharas Dam was accomplished. The second <br />occurrence of reduced releases from Pueblo Dam and storage of flood <br />waters (between June I and June 10) was also due to another large inflow <br />into Cucharas Reservoir and threatening the dam with possible failure. <br /> <br />. <br /> <br />No flood control operation occurred on Ruedi Reservoir this year. <br /> <br />The Corps of Engineers estimated flood control benefits at Pueblo Dam <br />to be $90,000. <br /> <br />Table 12 shows the flood control benefits received on both Ruedi and <br />Pueblo Dams. <br /> <br />. <br /> <br />16 <br />
