<br />bOO!20 <br /> <br />- 6 - <br /> <br />12. La Plata River at the Colorado-New Mexico State Line. <br />The published record covers the entire study period. <br />13. Mancos River near Towoac, Colorado. <br />Monthly records are published from October, 1934 through <br />September, 1943 and from March, 1951 through September, 1954. <br />Annual values for 1944 through 1951 were estimated by cqrrelation <br />with the sum of the East, Middle and West Mancos Rivers near <br />Mancos for the period of concurrent record. <br /> <br />14. McElmo Creek near Cortez, Colorado. <br />For the period 1934 through 1940 annual values were taken <br />from the Record of the Engineering Advisory Committee to the <br />Upper Colorado River Compact Commission. Published records cover <br /> <br />from April, 1940 through September, 1945 and from October, 1950 <br />through September, 1952, and all of WY 1953-54. Annual values <br />for WY 1945-46 and WY 1952-53 were estimated from a revised <br /> <br />curve of precipitation at Rico correlated with runoff at Mancos <br />as derived originally by the Engineering Advisory Committee of <br />the Upper Colorado River Compact Commission. Monthly values for <br />the estimated years are the same percent of the annual as the <br />average monthly values are of the average annual discharge for <br />years of record. <br /> <br />15..
