SURFACE-WATER RECORDS
PERIOD OF RECORD - Oct. 1952 to Sept. 1995 (daily mean discharge), Oct. 1995 to current year (peak discharges greater than base discharge). PERIOD OF RECORD, Water-Quality.-- CHEMICAL DATA: Oct. 1968 to Sept. 1998. BIOCHEMICAL DATA: Oct. 1968 to Sept. 1998. PESTICIDE DATA: Oct. 1968 to Sept. 1998. PERIOD OF DAILY RECORD, Water-Quality.-- SPECIFIC CONDUCTANCE: Oct. 1993 to Sept. 1997. pH: Oct. 1993 to Sept. 1997. WATER TEMPERATURE: Oct. 1993 to Sept. 1997. DISSOLVED OXYGEN: Oct. 1993 to Sept. 1997.
GAGE - Water-stage recorder. Datum of gage is NGVD 1988, 2001 adjustment. Prior to Oct. 1, 2016, datum of gage 3.09 ft below NGVD 1929, 1973 adjustment, unadjusted for land-surface subsidence (4.526 ft below current datum). Satellite telemeter at station.
REMARKS - Major channel rectification completed late in the 1997 water year. No known regulation or diversions. Low flow is largely sustained by wastewater effluent from municipal and industrial uses. Stage-discharge relation is tidally affected at low flow. Some records listed in the "Period of Record" for surface water and water quality may not be available electronically.
AVERAGE DISCHARGE FOR PERIOD OF RECORD - 43 years (water years 1953-95), 96.5 ft³/s (69,900 acre-ft).
