GAGE - Water-stage recorder. Datum of gage is 1131.397 ft. above NADV88 on 09/30/2022. Prior datum of gage was 1,131.20 ft above NGVD of 1929; 1331.397 ft above NAVD88 . Prior to Apr. 9, 1971, at site 0.3 mi downstream at same datum. Satellite telemeter at station.
REMARKS - No known regulation. There are several small diversions above station for irrigation. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.
EXTREMES OUTSIDE PERIOD OF RECORD - The maximum stage since at least 1892, about 33 ft July 2, 1932, from information by local residents. A flood in the middle 1800's reached a stage of nearly 63 ft. Information indicates that a flood in 1858 covered the townsite of Sabinal. The stage would have been 70 to 80 ft, which seems unlikely. However, it is possible that a flood occurred in 1858 that covered part of the townsite and was higher than any flood since that date.
