> Site Information
LOCATION.--Lat 41°34'02.2", long 74°46'59.8" referenced to North American Datum of 1983, Sullivan County, NY, Hydrologic Unit 02040104, 1,500 ft downstream of the dam on Swinging Bridge Reservoir.
DRAINAGE AREA.--116 mi².  
PERIOD OF RECORD.--August 2019 to current year.
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 936.26 ft above NAVD of 1988.
REMARKS.--Entire flow regulated by powerplant and storage in Swinging Bridge Reservoir (station 01433000). Total flow includes a diversion from Cliff Lake (station 01433200) discharged through a tunnel into Swinging Bridge Reservoir (station 01433000).
Water Year 2019: Records fair. Water Year 2020: Records fair except those for estimated daily discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 1,250 ft³/s, Sept. 16, 2020, gage height, 6.34 ft; minimum discharge, 31 ft³/s, Aug. 27, 2019, gage height, 3.76 ft.
PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: August 2019 to current year. DISSOLVED OXYGEN: August 2019 to current year.
INSTRUMENTATION1.--A continuous water-quality monitor with water temperature, and dissolved oxygen provides 15-minute-interval readings.
REMARKS1.--Water temperature is affected by release of water from upstream reservoir. Interruption of record was due to malfunction of recording instrument.
EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: Maximum, 22.4 °C, Aug. 4, 2020; minimum, 0.0 °C, Dec. 21, 2019. DISSOLVED OXYGEN: Maximum, 15.1 mg/L, Dec. 20, 2019; minimum, 4.2 mg/L, Aug. 5, 2020.
