USGS Water-Year Summary 2022
LOCATION - Lat 32°35'19", long 104°25'17" referenced to North American Datum of 1983, Eddy County, NM, Hydrologic Unit 13060011, on downstream side of center pier of bridge on U.S. Highway 285, 0.4 mi south of Seven Rivers, 2.6 mi upstream from mouth, and 4.0 mi southwest of Lakewood. Mouth at Pecos River mile 480.9.
DRAINAGE AREA - 220 mi². (approximately)
REVISIONS HISTORY - Gage height and streamflow peaks for water years 2014-2016 were revised on January 31, 2020, based on changes to the gage datum and stage-discharge rating. Gage height for measurement 109 was removed during record revisions on January 31, 2020 because it was determined to be erroneous.
PERIOD OF RECORD - October 1963 to April 1997, May 1999 to current year.
GAGE - Water-stage recorder with satellite telemetry and crest-stage gage. Elevation of gage is 3,280 ft above NGVD of 1929, from topographic map. Prior to July 8, 1965, at site 400 ft upstream at datum 0.52 ft higher. Prior to May 20, 1999, at datum 2.19 ft higher.
REMARKS - Water years 2014-2019; records poor. Water year 2020; records good except for estimated discharges, which are poor. No surface diversions upstream from station; ground-water withdrawals for 240 acres, upstream from station. No flow most of time.
EXTREMES OUTSIDE PERIOD OF RECORD - Maximum discharge since at least 1941, about 30,000 ft³/s, gage height, 22.8 ft, from old debris on left bank, former site and datum, from rating curve extended above 5,700 ft³/s on basis of slope-area measurement at gage height 21.8 ft. Probable date of flood, Oct. 7, 1954.
