USGS Water-Year Summary 2021
03016000 ALLEGHENY RIVER AT WEST HICKORY, PA
LOCATION - Lat 41°34'15", long 79°24'29" referenced to North American Datum of 1927, Forest County, PA, Hydrologic Unit 05010003, on right bank at downstream side of bridge on State Highway 127 at West Hickory, 0.6 mi upstream from Siggins Run, 0.8 mi downstream from East Hickory Creek, at river mile 158.9.
DRAINAGE AREA - 3,660 mi².
REVISIONS HISTORY -

WDR PA-96-3: 1995(M).

Revisions: Peak discharge for water year 1995 previously reported on 2/9/1995 was revised to 12/8/1994 on 10/30/2019. The previously reported peak occurred during a period of backwater; the open water peak and associated gage height is now reported. The revision was originally reported in WDR PA-96-3 but was not actually revised until 10/30/2019

SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1941 to March 2006; October 2007 to current year.
GAGE - Water-stage recorder. Datum of gage is 1,059.90 ft above National Geodetic Vertical Datum of 1929 (from benchmark). Prior to Dec 12, 1941, non-recording gage at same site and datum. Satellite telemetry at station.
COOPERATION - Station established and maintained by the U.S. Geological Survey. Funding for this station is provided by the U.S. Army Corps of Engineers, Pittsburgh District, the Pennsylvania Department of Environmental Protection, and the U.S. Geological Survey.
REMARKS - Flow regulated since November 1949 by Chautauqua Lake, since October 1965 by Allegheny Reservoir (station 03012520) 39 mi upstream. Due to bridge construction, station operations were suspended Mar 21, 2006 through Oct 18, 2007. Records for water year 2014 rated good, except those for estimated daily discharges, which are poor. Records for water year 2015 rated good, except those for estimated daily discharges, which are poor. Records for water year 2016 rated good, except those for estimated daily discharges, which are poor. Records for water year 2017 rated good, except those for estimated daily discharges, which are poor. Records good for water year 2018 except those for estimated daily discharges, which are poor. Records good for water year 2019 except those for estimated daily discharges, which are poor.  No estimated daily discharge for water year 2020; records good.
ECOLOGICAL RECORDS
PERIOD OF RECORD - April 2002 to current year.
REMARKS - Samples were collected using rapid bioassessment protocols for benthic macroinvertebrates using a D-Frame net with a mesh size of 500 mm. Counts are based on a randomly-selected 100-organism (approximate) subsample.
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.
