This station is operated in cooperation with:
   NYS Department of Environmental Conservation
   U.S. Geological Survey


LOCATION.--Lat 42°27'48", long 78°56'03" referenced to North American Datum of 1983, Erie County, NY, Hydrologic Unit 04120102, on right bank 15 ft upstream from bridge on State Highways 39 and 62 at Gowanda, 4.2 mi downstream from South Branch, and 17.8 mi upstream from mouth.
DRAINAGE AREA.--436 mi2.
PERIOD OF RECORD.--November 1939 to March 1998, October 1999 to current year.
REVISED RECORDS.--WSP 2112: Datum. WDR NY-71-1: 1956 (M). WDR NY-74-1: 1940-42 (M). WDR NY-82-3: Drainage area. WDR NY-09-3: 1990-98, 2000-08 (P).
GAGE.--Water-stage recorder. Datum of gage is 738.85 ft above NGVD of 1929. Prior to Oct. 1, 1969, at datum 0.11 ft lower. Prior to May 29, 2011, at location 470 ft downstream at same datum.
REMARKS.--Records good except those for estimated daily discharges, which are fair. Diurnal fluctuation at low and medium flow caused by powerplant 20 mi upstream from station. Telephone and satellite gage-height telemeters at station.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 34,600 ft3/s, Mar. 7, 1956, gage height, 14.03 ft; minimum discharge, about 6 ft3/s, Aug. 21, 1941, result of regulation; minimum gage height, 0.90 ft, Oct. 26, 1951.
INSTRUMENTATION1.--ISCO refrigerated automatic sampler since June 2011. A YSI 6920-V2 continuous monitor with water temperature, specific conductance, pH, dissolved oxygen and turbidity since June 2011 provides 15-minute-interval readings.
EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: Maximum, 33.0°C, July 22, 2011; minimum, -0.1°C, on several days.
SPECIFIC CONDUCTANCE: Maximum, 590 µS/cm @ 25°C, Sept. 20, 21, 2011; minimum, 122 µS/cm @ 25°C, Oct. 28, 29 2011. pH: Maximum, 8.9, Apr. 29, 30, May 1, 2013; minimum, 7.7, Jan 29, 2013. DISSOLVED OXYGEN: Maximum, 14.7 mg/L, Jan. 8, 9, 2013; minimum, 6.7 mg/L, July 17, 2012. TURBIDITY: Maximum, >1,380 FNU, May 29, 2013; minimum, 3.0 FNU, Aug. 21, 22, 2013.[>, actual value is known to be greater than the value shown].
