DRAINAGE AREA - 14,300 mi² of which 2,940 mi² probably is noncontributing. (from the closed basin in San Luis Valley, Colorado)
REVISIONS HISTORY - WSP 828: drainage area. WSP 1512: 1895-99, 1904-06, 1911-12, 1914, 1931(M), 1935. WSP 1712: 1904(M). WDR-NM-90: 1989.
SURFACE-WATER RECORDS
PERIOD OF RECORD - February 1895 to December 1905, June 1909 to current year. Monthly discharge only for some periods, published in WSP 1312. In early reports this record was published as "at Water Tank," as "at Rio Grande," and as "near Buckman."
GAGE - Water-stage recorder with satellite telemetry and crest-stage gage. Datum of gage is 5,491.66 ft above NAVD of 1988, from GNSS survey. See WSP 1312, 1732, or 1923 for history of changes prior to June 1, 1910.
REMARKS - Water years 2014-2017; records fair except for estimated discharges, which are poor. Water years 2018-2020; records good except for estimated discharges, which are poor. Considerable regulation by Heron Reservoir (station 08284510), El Vado Reservoir (station 08285000), and Abiquiu Reservoir (station 08286900) on Rio Chama, which can contribute a major portion of the total flow. Flow affected by release of transmountain water from Heron Reservoir since May 1971. Diversions upstream from station for irrigation of about 620,000 acres in Colorado and 75,000 acres in New Mexico.
EXTREMES OUTSIDE PERIOD OF RECORD - The 1920 flood is greatest since at least 1884 and probably since 1741; information from file of W.H. Yeo on floods.
