This station is operated in cooperation with:
   NYS Department of Environmental Conservation


LOCATION.--Lat 43°27'06", long 76°30'19" referenced to North American Datum of 1983, Oswego County, NY, Hydrologic Unit 04140203, on right bank at New York State Barge Canal (Oswego Canal) Lock 7 in Oswego, 0.8 mi upstream from mouth.
DRAINAGE AREA.--5,100 mi2.
PERIOD OF RECORD.--October 1900 to April 1906, October 1933 to current year. Monthly discharge only for some periods, published in WSP 1307. Prior to January 1904, published as "above Minetto" or "near Minetto." January 1904 to April 1906, published as "at Battle Island." Records for April 1897 to September 1900, published in WSP 65 and for October 1927 to September 1928, published in WSP 644, have been found to be unreliable and should not be used.
REVISED RECORDS.--WDR NY 78-1: Drainage area.
GAGE.--Water-stage recorder. Datum of gage is 245.12 ft above NGVD of 1929. Prior to October 1933, nonrecording gage at site about 6 mi upstream at different datum.
REMARKS.--Records good. No estimated daily discharges. Prior to 1933 and subsequent to 1972, flow in Oswego (Barge) Canal not included. A large amount of natural storage and some artificial regulation is afforded by the many large lakes and the Erie (Barge) and Oswego (Barge) Canal systems in the river basin. Large diurnal fluctuations at low and medium flow caused by powerplants upstream from station. Oswego River basin receives water from Erie (Barge) Canal through Lock 32 near Pittsford. Water may be diverted into or received from Mohawk River basin through Erie (Barge) Canal between New London and Utica. During part of year, entire flow from 45.5 mi2 of Mud Creek drainage area may be diverted from Chemung River basin into Keuka Lake in Oswego River basin. Nearly all of the flow from 14 mi2 of the Tioughnioga River basin may be diverted into De Ruyter Reservoir, in Oswego River basin. Telephone and satellite gage-height telemeters at station.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 37,500 ft3/s, Mar. 28, 1936, includes daily mean discharge of canals; maximum gage height, 13.46 ft, Apr. 10, 1940; minimum discharge (river only), 30 ft3/s, Nov. 6, 1944.
INSTRUMENTATION1.--ISCO refrigerated automatic sampler since July 2010. A YSI 6920-V2 continuous monitor with water temperature, specific conductance, pH, dissolved oxygen and turbidity since December 2010 provides 15-minute-interval readings.
EXTREMES FOR PERIOD OF DAILY RECORD1.--WATER TEMPERATURE: Maximum, 29.5°C, July 17, 2012; minimum, -0.1°C, on several days during winter period.
SPECIFIC CONDUCTANCE: Maximum, 1,080 µS/cm @ 25°C, Feb. 20, 2011; minimum, 388 µS/cm @ 25°C, May 2, 2011. pH: Maximum, 9.2, on several days; minimum, 7.3, Jun. 28, 2012. DISSOLVED OXYGEN: Maximum, 15.9 mg/L, Feb. 26, 28, Apr. 17, 2012; minimum, 3.3 mg/L, Aug. 6, 2012. TURBIDITY: Maximum, 62 FNU, Sept. 7, 2011; minimum, 0.0 FNU, Sept. 14, 2012 [0.0 FNU may have occurred on days of missing record or instrument malfunction].
