GAGE - Water-stage recorder. Datum of gage is NAVD 1988, 2001 adjustment. Prior to Oct. 1, 2008, datum of gage 1.40 ft below NGVD of 1929 (3.14 ft above current datum); records unadjusted for land-surface subsidence.

Extreme low flow is sustained by drainage from irrigated lands, and from minor wastewater effluent. No flow at times. Gage height associated with historical peak discharge is referenced to datum then in use. 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 1896, 85.6 ft (datum then in use) in Dec. 1935, adjusted to former site from floodmark 0.5 mi downstream, on basis of slope of flood of Aug. 29, 1945, from information by local resident.
