USGS Water-Year Summary 2019
LOCATION - Lat 38°55'00.5", long 76°58'09.2" referenced to North American Datum of 1983, Washington, DC, Hydrologic Unit 02070010, on left bank, 75 ft downstream from New York Avenue, and approximately 1000 ft west of entrance to National Arboretum.
DRAINAGE AREA - 0.99 mi². from automated delineation using 30-meter National Elevation Dataset, digital elevation model data, dated 2006.
REVISIONS HISTORY - https://waterdata.usgs.gov/nwis/dv/?site_no=01651770: 2013
PERIOD OF RECORD - October 2012 to current year.
GAGE - Water stage recorder and crest-stage gage. Datum of gage is 17.16 ft above North American Vertical Datum of 1988.
  • Water Years 2017-2018: Records poor, including those for estimated discharges.
  • Water Year 2016: Records poor, including those for estimated daily discharges.
  • Water Year 2015: Records poor. No estimated daily discharges.
  • Water Year 2014: Records poor, including those for estimated daily discharges.
  • Water Year 2013 record accuracy statement can be found in the Annual Water Data Report.

  • U.S. Geological Survey water-data telemeter at station.
    PERIOD OF RECORD - January 2013 to current year.
    PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: January 2013 to current year. WATER TEMPERATURE: January 2013 to current year. TURBIDITY: January 2013 to current year.
    INSTRUMENTATION - Water-quality monitor, January 2013 to current year.
    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.

WATER TEMPERATURE: Maximum, 31.2°C, on September 3, 2018 ; minimum, 0.8°C, on February 21, 2015. TURBIDITY: Maximum, 1,090 formazin nephelometric units (FNU), March 13, 2013; minimum, 0.0 formazin nephelometric units (FNU), April 26, 28, 2013.
