USGS Water-Year Summary 2021
LOCATION - Lat 35°37'04.8", long 106°19'26.2" referenced to North American Datum of 1983, Sandoval County, NM, Hydrologic Unit 13020201, in Pueblo de Cochiti Grant, on right bank 320 ft upstream from bridge on State Highway 22, 700 ft downstream from Cochiti Dam, 1.4 mi northeast of Cochiti Pueblo, and at mile 1,587.6.
DRAINAGE AREA - 14,900 mi². (approximate, and also includes 2,940 mi2 in closed basin in San Luis Valley, Colorado)
PERIOD OF RECORD - October 1970 to current year.
GAGE - Water-stage recorder with satellite telemetry and crest-stage gage. Datum of gage is 5,229.01 ft above NAVD of 1988. Prior to Nov. 14, 1973, at site 2.4 mi downstream at elevation 5,210 ft, from topographic map. Nov. 14, 1973, to Jan. 8, 1976, at site 320 ft downstream at datum 1.79 ft lower.
REMARKS - Water years 2014-2020; records good except for estimated discharges, which are poor. Discharges include flow of Santa Fe River, which is intercepted by Cochiti Dam and released through the combined outlet works. Flow regulated by Cochiti Dam since Nov. 12, 1973. Diversions upstream from station for irrigation of about 620,000 acres in Colorado and about 81,000 acres in New Mexico. Cochiti Eastside Main canal, on left bank, and Sili Main canal, on right bank, head at Cochiti Dam and bypass gage for irrigation of about 6,000 acres downstream from station.
EXTREMES OUTSIDE PERIOD OF RECORD - The flood of May 15, 1941, reached a discharge of 23,400 ft³/s at a nearby site upstream from mouth of Santa Fe River. The flood of May 23, 1920, probably exceeded 23,400 ft³/s and is likely the highest since 1905.
PERIOD OF RECORD - July 1971 to October 1988, September 1991, September 1994, July 1996, July 2000 to current year.
SPECIFIC CONDUCTANCE: October 1974 to September 1984, October 1986 to August 1987, September 2000 to July 2001, November 2002 to current year.
WATER TEMPERATURE: July 1971 to September 1982, September 2000 to July 2001, November 2002 to current year.
PH: September 2000 to July 2001, November 2002 to current year.
DISSOLVED OXYGEN: September 2000 to July 2001, November 2002 to current year.
TURBIDITY: September 2000 to July 2001, November 2002 to current year.
SUSPENDED-SEDIMENT DISCHARGE: July 1974 to September 1984, October 1985 to September 1988.
INSTRUMENTATION - Water-quality monitor since September 2000. Electronic data logger with 15-minute recording interval except for periods September 2000 to July 2001 and March 2007 to November 2017, when the recording interval was 60 minutes, and period August 2001 to October 2002, when the water-quality monitor was inactive. Turbidity reported as Nephelometric Turbidity Units (NTU) prior to water year 2005. NTU and Formazin Nephelometric Units (FNU) values are equivalent below 300.
