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.

WATER-QUALITY RECORDS
PERIOD OF DAILY RECORD - WATER TEMPERATURE: September 2022 to current year. SPECIFIC CONDUCTANCE: September 2022 to current year. DISSOLVED OXYGEN: September 2022 to current year. PH: September 2022 to current year. The four parameters are operated seasonally.
COOPERATION - Station established by the US Geological Survey in cooperation with the Pennsylvania Department of Environmental Protection.
INSTRUMENTATION - Water-quality monitor collecting data at 15-minute interval. Iridium Satellite telemetry at the station.
REMARKS - Water temperature, specific conductance, pH, and dissolved oxygen data collection is suspended during the winter months. Cross-sectional water quality 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.
EXTREMES FOR PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Maximum, 416 microsiemens/cm Jun 12, 2023; minimum, 106 microsiemens/cm, May 3, 2023. PH: Maximum, 9.1 standard units, Aug 6, 2023; minimum, 7.0 standard units, Sep 11, 2023. WATER TEMPERATURE: Maximum, 28.9°C, Jul 8, 2023; minimum, 10.0°C, Oct 20, 2022. DISSOLVED OXYGEN: Maximum, 12.7 mg/L, Apr 21, May 15, and Aug 6, 2023; minimum, 6.2 mg/L Aug 8, 2023.
