GAGE - Water-stage recorder, crest-stage gage, water-quality monitor, and weighing bucket precipitation gage. Datum of gage is 1,244.00 ft above North American Vertical Datum of 1988. Prior to October 2, 2023, the datum of gage was reported as 1,244.60 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 in cooperation with the U.S. Army Corps of Engineers, Philadelphia District.

WATER-QUALITY RECORDS
PERIOD OF DAILY RECORD - Water Temperature: Jul 1988 to Sep 2004. Oct 2017 to current year.
REMARKS - Cross-sectional water temperature data is available upon request. Historically water temperatures below 0 degrees Celsius were not reported. Water temperature sensors now have the ability to accurately read water temperatures below 0 degrees Celsius. Subsequent to water year 2015, water temperatures below 0 degrees Celsius are reported. Water temperature records for water year 2018 are good Oct 1 to Nov 21, and Dec 13 to Sep 30, and are poor Nov 22 to Dec 12. Beginning in water year 2019, water quality records are not rated as "excellent", "good", "fair", or "poor".
EXTREMES FOR PERIOD OF DAILY RECORD - Water Temperature: Maximum, 27.5° C, Jul 6, 1999; minimum 0.0°C, many days during winter periods.
