The average <br />annual runoff from the roughly 2.5 square mile watershed downstream from the <br />Colorado Springs reservoirs to the Victor No.2 reservoir is estimated to approxi- <br />mate 900 acre-feet. During dry years the 2.5 square mile watershed downstream <br />from the Colorado Springs reservoirs to the Victor No.2 Reservoir is estimated <br />to produce 247 acre-feet. As a point of reference, Victor No.2 Reservoir is <br />estimated to contain 210 acre-feet at its original spillway crest elevation of <br />10,392 feet. <br /> <br />As this is a rehabilitation project of an existing project, we are further able to <br />estimate the abil ity of the basin to provide an adequate water supply to best <br />utilize the reservoirs by presenting documentation of the water depths historically <br />stored. An analysis of available records is shown on Table 4.4. Although this <br />table represents sparse data, it does generally show that the reservoir to be <br />spilling from July to September. <br /> <br />Based on the Woodward & Clyde determined yield of surface flows and backed up by <br />the historical use within the City's system, it appears that adequate surface <br />water supplies are available to meet the projected population and water use <br />th rough the yea r 2026. <br /> <br />Table 4.5 shows calculated daily water production, maximum supply rate, peak <br />consumption, required fire flow, and maximum storage requirements to meet the <br />projected future water requirements calculated as a part of Table 4.2. <br /> <br />23 <br />
