03029500 CLARION RIVER AT COOKSBURG, PA
LOCATION - Lat 41°19'50", long 79°12'33" referenced to North American Datum of 1927, Clarion County, PA, Hydrologic Unit 05010005, on right bank at downstream side of bridge on State Highway 36 at Cooksburg, 300 ft downstream from Toms Run, and 2.7 mi upstream from Cathers Run.
DRAINAGE AREA - 807 mi².
REVISIONS HISTORY - WSP 1305: 1939 (M). WDR PA-85-3: 1979 (M). WDR-US-2007: 2006. WDR-US-2011: 2004.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1938 to current year. Monthly discharge only for October, November 1938, published in WSP 1305.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 1,147.00 ft above National Geodetic Vertical Datum of 1929 (from benchmark). Prior to May 17, 1939, non-recording gage at same site and datum. Satellite telemetry at station.
COOPERATION - Funding for the operation of this station is provided by Brookfield Power, the Pennsylvania Department of Environmental Protection, and the U.S. Geological Survey.
REMARKS -

Flow regulated since June 1952 by East Branch Clarion River Lake (station 03027000) and at low flow by industrial plants above station. Records for water year 2014 are good except those for estimated daily discharges, which are poor. Records for water year 2015 are good except those for estimated daily discharges, which are poor.

Records for water year 2017 are good except those for estimated daily discharges, which are poor.

Records for water year 2018 are good except those for estimated daily discharges, which are poor.

Records for water year 2019 are good except those for estimated daily discharges, which are poor.

Records for water year 2020 are good except those for estimated discharges, which are poor.

EXTREMES OUTSIDE PERIOD OF RECORD - Maximum stage since 1935, 19 ft, Mar 17, 1936, from floodmarks, discharge, about 56,000 ft³/s.
WATER-QUALITY RECORDS
PERIOD OF RECORD - April 2002 to current year.
COOPERATION - Water-quality samples were collected as part of the Pennsylvania Department of Environmental Protection Water-Quality Network (WQN) with cooperation from the Pennsylvania Department of Environmental Protection.
REMARKS - As of October 2013, results from discrete water quality samples collected at this site are available through the U.S. Geological Survey National Water Information System web interface on the "Water Quality for the Nation" webpage. Analyses for pH, water temperature, specific conductance, and dissolved oxygen were performed on site. All other sample analyses were performed at the Pennsylvania Department of Environmental Protection laboratory in Harrisburg, PA. Occasionally, values for filtered parameters may exceed values for the corresponding unfiltered parameter. These results are within the limits of analytical precision and methods.
