The drainage basin is 230 square miles. <br /> <br /> <br />Records are available for the period of May 1926 to September 1929, April <br /> <br /> <br />1940 to September 1945, October 1950 to September 1954, and January 1982 <br /> <br /> <br />through 1984. The accuracy of streamflow records is considered to be good <br /> <br /> <br />except for the winter months, which are poor. The flow mainly consists of <br /> <br /> <br />return flows from irrigated lands of the Montezuma lJ:Tigation District, with <br /> <br /> <br />water imported from the Dolores River basin. <br /> <br />McE1mo Creek below Cortez <br /> <br /> <br />The gage is located downstream of Sand Canyon and about 12 miles west <br /> <br /> <br />of Cortez.

Records are considered <br /> <br /> <br />to be good except for winter months, which are fair. The flow consists mainly <br /> <br /> <br />of irrigation return flows from Dolores River diversions. Diversions above the <br /> <br /> <br />gaging station are made by the Rock Creek Ditch for in-igation of about 650 <br /> <br /> <br />acres below the station. <br /> <br />McEImo Creek near Colorado-Utah State Line <br /> <br /> <br />The gage is located 1.5 miles upstream of the Colorado-Utah state line <br /> <br /> <br />and about two miles upstream from the confluence with Yellowjacket Creek. <br /> <br /> <br />The drainage area is about 346 square miles. Records are available for the <br /> <br /> <br />period of 1951 through 1984. The accuracy of streamflow records is considered <br /> <br /> <br />to be good. Most of the flow of McElmo Creek is contributed by return flows <br /> <br /> <br />from irrigated lands of the Montezuma lJ:Tigation District, with water imported <br /> <br /> <br />from the Dolores River basin. <br /> <br />Summaries of gage records are presented in Appendix A of this report. <br /> <br />-4- <br /> <br />~ ,,~-~-'-' <br />
