GAGE - Water-stage recorder,  crest-stage gage, and weighing bucket precipitation gage. Datum of gage is 586.33 ft above National Geodetic Vertical Datum of 1929. Aug 1925 to Sep 16, 1926, non-recording gage, and Sep 17, 1926, to Jun 13, 1988, water-stage recorder at site 500 feet downstream on left bank at same datum. Satellite and landline telemetry at station.
COOPERATION - Station established and maintained by the U.S. Geological Survey in cooperation with the Pennsylvania Department of Environmental Protection.
REMARKS - Highest daily mean flow for period of record is an estimated value. Records for water year 2014 are rated good except those for estimated daily discharges, which are poor. Records for water year 2015 are rated good except those for estimated daily discharges, which are poor. Records for water year 2016 are rated good except those for estimated daily discharges, which are poor. Records for water year 2017 are rated good except those for estimated discharges, which are poor. Records for water year 2018 are rated good except those for estimated discharges, which are poor.

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.
