<br />2858 <br /> <br />The discharge of the Mancos River and McElmo Creek are <br /> <br /> <br />4It measured at two Geological Survey gaging stations in or near <br /> <br /> <br />the project area. Records for the water years of 1957 and <br /> <br /> <br />1961 are shown in table 1. The station on the Mancos River <br /> <br />. <br /> <br />. <br /> <br />Table 1. <br /> <br />(p..:?'! of ms.) near here. <br /> <br />is 750 feet upstream [rom the bridge on U.S. Highway 666 <br /> <br /> <br />about 12 miles south of Towaoc. The average discharge at <br /> <br /> <br />this station for the past 29 years was 58.8 cfs (cubic feet <br /> <br /> <br />per second). Maximum recorded flow was 5,300 cfs on <br /> <br /> <br />October 14, 1941. The stream does not flow at times in <br /> <br />most years, particularly during September, October, and <br /> <br />November. Water is diverted above the station for irriga- <br />tion of about 100 acres at the Mancos farm, the only land <br />irrigated by surface water in the project area. <br />The discharge of McElmo Creek is measured at a gaging <br />station l~ miles east of the Utah State line, a few miles <br />outside the project area. The average discharge at this <br />station for 6 years was 36.2 cfs. Maximum recorded discharge <br />was 1,700 cfs on August 29, 1951, and July 27, 1957. Minlffium <br />flows of 0.1 cfs were recorded several days in 1951 and 1957. <br />Water is diverted bet\"een the station and the reservation <br /> <br />for irrigation of about 1,000 acres of land above the station <br />and 60 acres below it. <br /> <br />,,",~i' <br />
