USGS Water-Year Summary 2021
LOCATION - Lat 39°03'29.9", long 75°23'51.4" referenced to North American Datum of 1983, Kent County, DE, Hydrologic Unit 02040207, at Bowers Beach, on left bank, southeast corner of public pier, 10 ft west of triple public boat ramp, and about 500 ft upstream of mouth.
DRAINAGE AREA - 104 mi².

Gage heights for the period of February 27, 2018, to June 12, 2019, were revised on July 24, 2020, based on a documented difference to a gage-height correction originally applied during the listed period.

https://nwis.waterdata.usgs.gov/md/nwis/uv?site_no=01484085: 2018-2019.

PERIOD OF RECORD - July 1965 to October 1990 (crest-stage gage only), October 1996 to November 2006 (stage only), November 2006 to June 2009 (stage and discharge), June 2009 to November 2011 (stage only), November 2011 to September 2016 (stage and discharge), October 2016 to current year (stage only).
GAGE - Water-stage recorder. Datum of gage is 0.00 ft above North American Vertical Datum of 1988. (Mean Low-Low Water: Gage Datum + 1.92 ft) October 2011 to current year. Prior to October 2011, datum of gage was 0.00 ft above National Geodetic Vertical Datum of 1929. July 1965 to July 22, 1984, at site 500 ft upstream at same datum (NGVD 29). July 23, 1984 to October 1990, and October 17, 1996 to September 21, 2006, at site 500 ft upstream at datum 1.02 ft higher (NGVD 29). September 22, 2006 to September 30, 2009, at present site, at datum 1.02 ft higher (NGVD 29).
  • Water Year 2020: Gage-height record fair.
  • Water Year 2019: Gage-height record good. Missing data due to removal of small periods of questionable record.
  • Water Years 2017-2018: Gage-height record good. Missing data due to equipment malfunction.
  • Water Year 2016: Gage-height record good and discharge record fair. Missing data due to equipment malfunction.
  • Water Year 2015: Gage-height record fair and discharge record fair from October 2014 to June 2015, and poor from July to September 2015. Missing data due to equipment malfunction.
  • Water Year 2014: Gage-height record good and discharge record fair. Missing data due to equipment malfunction.
  • Water Year 2013 and prior years' accuracy statements can be found in Annual Water Data Reports.

  • This is a tidal station. Discharge is not determined at this location. U.S. Geological Survey satellite data-collection platform at station.
