Water-Year Summary for Site 01549700

Click to hide 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.

USGS Water-Year Summary 2023
LOCATION - Lat 41°16'25", long 77°19'28" referenced to North American Datum of 1927, Lycoming County, PA, Hydrologic Unit 02050205, on left bank along State Highway 44, on abutment of abandoned bridge 0.9 mi downstream from Ramsey Run, 4.0 mi downstream from Little Pine Creek, 4.0 mi south of Waterville, and 9.2 mi upstream from mouth.
DRAINAGE AREA - 944 mi².
PERIOD OF RECORD - October 1957 to current year.
GAGE - Water-stage recorder, crest-stage gage, and water-quality monitor. Datum of gage is 570.62 ft above National Geodetic Vertical Datum of 1929. Prior to Jun 16, 1982, non-recording gage at same site and datum. Satellite and landline telemetry at station.
COOPERATION - Station established and maintained by the U.S. Geological Survey. Funding for the operation of this station is provided by the Pennsylvania Department of Environmental Protection and the U.S. Geological Survey.
REMARKS - Flood flows subject to regulation by Little Pine Dam 8.5 mi upstream, capacity 24,900 acre-ft. Records are good except those for estimated discharges, which are poor.
PERIOD OF RECORD - April 2002 to current year.
PERIOD OF DAILY RECORD - WATER TEMPERATURE: November 2010 to current year. SPECIFIC CONDUCTANCE: November 2010 to current year. DISSOLVED OXYGEN: June 2011 to current year, seasonal operation. pH: June 2011 to current year, seasonal operation.
COOPERATION - Station established by the US Geological Survey in cooperation with the Pennsylvania Department of Environmental Protection. 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 - Water temperature and specific conductance data are collected year round. pH and dissolved oxygen data collection is suspended during the winter months. Cross-sectional water quality data is available upon request. 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. 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. 

SPECIFIC CONDUCTANCE: Maximum, 293 microsiemens/cm, Feb 13, 14, 2011; minimum, 43 microsiemens/cm, Apr 28, 2011.

WATER TEMPERATURE: Maximum, 33.8°C, Jul 22, 2011; minimum, 0.0°C or below, several days during winter periods. 

PH: Maximum, 9.6 standard units, Jun 8,9, 2019; minimum, 6.3 standard units, Sep 9, 2011.

DISSOLVED OXYGEN: Maximum, 15.0 mg/L Apr 17, 2014; minimum, 3.8 mg/L July 25, 2022.
