Click to hide Water-Year Summary instructions and information
  • Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
  • For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
  • For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
  • For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
  • Not all sites have reports available for every water year.

USGS Water-Year Summary 2021
LOCATION - Lat 40°37'40", long 80°20'16" referenced to North American Datum of 1927, Beaver County, PA, Hydrologic Unit 05030101, on left bank at downstream side of highway bridge at Moffatts Mill, 1.4 mi downstream from Gums Run, 4 mi south of Vanport, and 4.2 mi upstream from mouth.
DRAINAGE AREA - 178 mi².

WSP 1385: 1941-43.

Revisions: Discharge for the period of July 3, 2018 to July 9, 2018 was revised on March 28, 2019, based on additional estimation information 

PERIOD OF RECORD - September 1941 to current year. May 1915 to July 1932 (gage heights and discharge measurements only) in reports of Water Supply Commission of Pennsylvania and Pennsylvania Department of Forests and Waters.
GAGE - Water-stage recorder. Datum of gage is 719.16 ft above National Geodetic Vertical Datum of 1929 (U.S. Army Corps of Engineers benchmark). May 27, 1915 to July 31, 1932, and Sept. 2 to Dec. 3, 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 the operation of this station is provided by the Pennsylvania Department of Environmental Protection and the U.S. Geological Survey.
REMARKS - Normally, no regulation from Raccoon Lake. Some diversion upstream for water supply. Published records do not include diversion. Records for water year 2014 are good except those for estimated daily discharges, which are poor.   Records for water year are good except those for estimated discharges, which are poor.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of Apr. 15, 1922, reached a stage of 9.80 ft, discharge, 10,000 ft³/s. Flood of Mar. 5, 1920, also reached a stage of 9.80 ft, as a result of backwater from ice.
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.
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.
