H. Storage Contracts There were eight contracts for storage of non - project water in project storage space on the east slope in effect in water year 2005. Six of those were long -term contracts: the Twin Lakes Reservoir and Canal Company for 54,452 acre -feet; the City of Colorado Springs for 17,416 acre -feet; the City of Aurora for 5,000 acre - feet; the Pueblo Board of Water Works for 5,000 acre -feet; Busk - Ivanhoe, Inc., for 10,000 acre -feet; and the Homestake Project for 30,000 acre -feet. There was one long -term, non -firm contract for Pueblo Board of Water Works. The remaining contracts were interim one -year contracts for "if -and- when" storage space. Under "if- and - when" contracts, non - project water may be stored in project storage space as long as that storage space is not required for project water. I. Proiect Water Sales and Deliveries The project made available 40,800 acre -feet of water to the Southeastern Colorado Water Conservancy District during water year 2005. The district purchased 44,482 acre -feet and called for 20,985 acre -feet of project and project carryover water during the year. Evaporation reduced the project water in storage by 5,647 acre -feet. By the end of the water year (September 30, 2005), the district had 27,898 acre -feet of 2005 allocated water and 49,170 acre -feet of carryover water remaining in storage. Of the 20,985 acre -feet of project water released, 4,173 acre -feet were for municipal and industrial use, and 16,812 acre -feet were for irrigation. The monthly release of project water from Pueblo Reservoir is shown on Exhibit 21. J. Reservoir Storage Allocation Data Table 9 presents the reservoir storage allocations for the five project reservoirs. K. Reservoir Evaporation and Precipitation Tables 11 and 12 present the monthly average evaporation and precipitation at the four weather stations near project facilities. When an evaporation pan is not in service and a reservoir is not completely ice - covered, the daily water surface evaporation is computed using seasonal evaporation factors. Those factors are listed in Table 10. It is assumed that there is no evaporation from a reservoir water surface when the reservoir is completely covered by ice. L. Flood Control Benefits The Corps of Engineers determined that neither Pueblo Reservoir nor Ruedi Reservoir prevented any flood damage in water year 2005. Table 13 shows the historic flood control benefits provided by Pueblo and Ruedi Dams.
