REVISIONS HISTORY - Prior to 5/22/23 the datum of the gage was 3129 ft above NGVD29 (determined via topographic map).
SURFACE-WATER RECORDS
PERIOD OF RECORD - January 1973 to current year.
GAGE - Water-stage recorder with satellite telemetry and crest-stage gage. Datum of gage is 3089.75 ft above NAVD88 as determined by a GNSS Level II rapid-static survey performed by the USGS on June 18, 2020. 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 2014-2021; records good except for estimated discharges, which are fair. Water years 2022-2023; records good. 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.

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.
