Water-stage recorder. Satellite telemetry at station.

Datum of gage: 400.155 ft NAVD88 based on a Level 2 Static GNSS survey processed through OPUS, Ref Frame NAD83 (2011)(EPOCH:2010.0000) ITRF2014 (EPOCH:2023.6212) and Geoid 18. The survey was completed on August 15, 2023, while occupying RM3.

REMARKS - Records fair. Since Mar. 1954, at least 10% of contributing drainage area has been regulated. Wastewater effluent is returned upstream of station from Fort Hood military installation and by the cities of Killeen, Nolanville, and Harker Heights. Many small diversions upstream for irrigation and municipal supply affect very low flow. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.
EXTREMES OUTSIDE PERIOD OF RECORD - Maximum stage since at least 1900, 46.8 ft in Sept. 1921, from information by local residents.
