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 2019
LOCATION - Lat 39°21'41.7", long 76°45'42.3" referenced to North American Datum of 1983, Baltimore County, MD, Hydrologic Unit 02060003, on left bank at upstream side of bridge on Rolling Road, 0.40 mi northeast of Liberty Road (State Route 26), and 0.50 mi upstream from mouth.
DRAINAGE AREA - 3.23 mi².
REVISIONS HISTORY - WDR-US-2009: 2006-2008.
PERIOD OF RECORD - October 2005 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 452.36 ft above North American Vertical Datum of 1988.
  • Water Years 2018-2019: Records fair, except those for estimated discharges, which are poor.
  • Water Year 2017: Records fair, no 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 satellite data-collection platform at station.
    PERIOD OF RECORD - WATER TEMPERATURE: Jan 2016 to current year. SPECIFIC CONDUCTANCE: Jan 2016 to current year. TURBIDITY: Oct 2015 to current year.
    INSTRUMENTATION - Water-quality monitor October 2015 to current year.

    Turbidity values greater than 1,600 nephelometric turbidity units (NTU) exceed the instrument calibration range. Values are included in the record but are presumed to have lower precision.

    Water quality values that were determined to be a result of debris on the sensor, a function of incident sun angle, or other phenomena that did not appear to be correlated to suspended-sediment concentration were removed by the hydrographer. Extended periods of missing data are due to equipment malfunctions.

    EXTREMES FOR PERIOD OF DAILY RECORD - WATER TEMPERATURE: Maximum, 28.2°C, August 14, 2016; minimum, -0.2°C, on February 16, 2016.

    SPECIFIC CONDUCTANCE: Maximum, 15800 microsiemens per centimeter, February 16, 2016; minimum, 35 microsiemens per centimeter, July 30, 2016.

    TURBIDITY: Maximum, 1880 formazin nephelometric units (FNU), November 15, 2018; minimum, 0.0 formazin nephelometric units (FNU), multiple occurrences, first occurrence on October 16, 2016.
