REVISIONS HISTORY -

WSP 743: Drainage area. WSP 1385: 1919, 1936-39. WDR PA-72-1: 1923 (M), 1926 (M), 1928 (M), 1936, 1937 (M), 1938 (M), 1943, 1945 (P), 1952 (M), 1953 (M), 1955 (M), 1956 (P), 1958 (M), 1959 (M), 1964, 1966 (M). See also PERIOD OF RECORD.

Revisions: Gage Height and Discharge for the period of May 5, 2020 - June 19, 2020 were revised on August 7, 2020 due to a change in the gage height correction.

SURFACE-WATER RECORDS

PERIOD OF RECORD - Annual maximums, water years 1910-18. October 1918 to current year. Monthly discharge only for some periods, published in WSP 1305. Figures of daily discharge for November 1920 to June 1921, published in WSP 523, are unreliable and should not be used.

GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 972.5 ft above North American Vertical Datum of 1988 (from benchmark). Prior to Jul 10, 1940, non-recording gage at site 500 ft upstream at datum 3.10 ft higher. Satellite telemetry at station. Prior to November 9, 2022, the datum of gage was reported as 973.14 ft above NGVD29.

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 - Records are rated good except those for estimated discharges, which are poor.

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.
