depleting the artificial flow into Rapid Creek. The inevitable impact on the water right holders will be the decrease of available water for irrigation. The water users of record on Rapid Creek and listed in Table 7-5. A water containment structure in the NW1/4 of Section 2, T11S, R98W has previously been identified as a spring. The Benitendi spring is actually on record as an alluvial well. The information on file with the Colorado State Water Resource Division is set forth in Figure 7-1. There is also one shallow alluvial well next to the river near Cameo Power Plant owned by Public Service Company of Colorado. This well is approximately 42 feet deep, with a permitted production rate of 60 gpm. Water is pumped from the Colorado River alluvium, and use of this well is limited to periods when water is not available on the Government Highline Canal. This well is outside the permit boundary and the adjacent area, and it will not be affected by • mining. A description of the well is presented in Figure 7-2. The quantity, peak stages, discharges, and seasonal variations of flow in the Colorado River have been recorded by the U.S. Geological Survey at gauging station number 955 located seven miles north of the permit area. (See Exhibit 7). This station has been monitored since 1934. The drainage area at the station is approximately 8,050 square miles. Seasonal distribution of discharge and flow duration are represented in Figure 7-3. Discharge rates, maximum, minimum, and average flows for water year 1978 and for the life of the station are shown in Table 7-7. The Colorado River has an average annual flow of 3,801 cubic feet per second over a 45-year period. The maximum daily discharge occurred in 1935 and was 36,000 cubic feet per second. The minimum daily discharge occurred in 1939 and was 700 cubic feet per second. Flows iri excess of 11,000 cubic feet per second • 7-14 (New 3/1 /96)
