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.

https://waterdata.usgs.gov/nwis/dv/?site_no=01651800: 2008-2018.

The date of measurement 151 was revised on November 21, 2019.

PERIOD OF RECORD - June 1992 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 10.73 ft above North American Vertical Datum of 1988 (NAVD88). June 1992 to Sept. 30, 2007, at site 210 ft upstream at gage datum 5.00 ft higher (15.73 ft above NAVD88). October 1, 2007 to September 30, 2008 at site 10 ft upstream at gage datum 5.00 ft higher (15.73 ft above NAVD88). October 1, 2008 to June 13, 2016, at site 10 ft upstream at current gage datum.  June 13, 2016 to current year, at current location and gage datum.
  • Water Years 2019-2021: Records fair, except those for estimated discharges, which are poor.
  • Water Years 2017-2018: Records poor, including those for estimated discharges.
  • Water Years 2014-2016: Records fair, except those for estimated daily discharges, which are poor.
  • Water Year 2013 and prior years' accuracy statements can be found in Annual Water Data Reports.

  • U.S. Geological Survey water-data telemeter at station.
    PERIOD OF RECORD - August 2012 to current year.
    PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: January 2013 to September 2013. WATER TEMPERATURE: January 2013 to September 2013. TURBIDITY: January 2013 to September 2013.
    COOPERATION - Funding for this station is provided by the United States Environmental Protection Agency Chesapeake Bay Program Office (USEPA/CBPO) in collaboration with the Washington, DC District Department of the Environment, and the U.S. Geological Survey.
    INSTRUMENTATION - Water-quality monitor January 2013 to September 2013.
    REMARKS - Turbidity values greater than 1,000 formazin nepthelometric units (FNU) exceed the instrument calibration range. Values are included in the record but are presumed to have lower precision. Missing record due to periodic instrument malfunction.
