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.

SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1950 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 216.60 ft above National Geodetic Vertical Datum of 1929. Satellite and landline 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, Philadelphia District, and the Pennsylvania Department of Environmental Protection.
REMARKS - Flow regulated since April 1979 by Blue Marsh Lake (station 01470870) 3.9 mi upstream. Records for water year 2014 are good except those for discharges less than 100 ft³/s, which are fair; no estimated daily discharges. Records for water years 2015, 2017-2018 are good except for discharge less than 100 ft³/s and for estimated discharge, which is fair. Records for water years 2016, 2019-2021 are good except for discharge less than 100 ft³/s, which is fair. Records for water years 2022-2023 are fair.
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.
