USGS Water-Year Summary 2020
LOCATION - Lat 32°24'12", long 104°13'46" referenced to North American Datum of 1983, Eddy County, NM, Hydrologic Unit 13060011, on right bank and upstream from San Jose Street, and 1.0 mi upstream from mouth. Mouth at Pecos River mile 459.2.
DRAINAGE AREA - 451 mi². (approximately)
PERIOD OF RECORD - January 1973 to current year.
GAGE - Water-stage recorder with satellite telemetry and crest-stage gage. Elevation of gage is 3,129 ft above NGVD of 1929. Prior to Aug. 19, 2002, at site 2,550 ft downstream at different datum (datum lost during reconstruction of the South Canal Street Bridge).
REMARKS - Water years 2014-2020; records good except for estimated discharges, which are fair. A Natural Resources Conservation Service flood-control project on Hackberry Draw, an upstream tributary, has some effect on flood peaks and flow duration. Ground-water withdrawals upstream from station for irrigation of approximately 2,100 acres, 1973 determination, and for municipal supply for Carlsbad. 
EXTREMES OUTSIDE PERIOD OF RECORD - The flood of Aug. 23, 1966, reached a discharge of 66,000 ft³/s, as determined by slope-area measurement at site 1.2 mi upstream. Another flood of approximately the same magnitude occurred Sept. 20, 1941. Other major peaks occurred July 17, 1906, July 24, 1908, July 24, 1911, Apr. 18, 1915, Aug. 8, 1916, Sept. 15, 1919, Aug. 4, 1925, and May 23, 1941.
