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 2020
01493112 CHESTERVILLE BRANCH NEAR CRUMPTON, MD
LOCATION - Lat 39°15'25.4", long 75°56'24.5" referenced to North American Datum of 1983, Kent County, MD, Hydrologic Unit 02060002, on middle pier of double box culvert at downstream side of State Highway 291, 1.2 mi upstream from mouth, and 1.5 mi northwest of Crumpton.
DRAINAGE AREA - 6.12 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - July 1996 to September 2002. June 2011 to current.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 1.21 ft above North American Vertical Datum of 1988.
REMARKS -
  • Water Years 2019-2020: Records good, except those above 50 ft³/s which are fair, and those above 100 ft³/s and those for estimated discharges, which are poor.
  • Water Year 2018: Records fair, except those above 100 ft³/s and those for estimated discharges, which are poor.
  • Water Year 2017: Records good, except those above 100 ft³/s and those for estimated discharges, which are poor.
  • Water Years 2015–2016: Records good, except those for estimated daily discharges, which are poor.
  • Water Year 2014: 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.

  • Flow occasionally affected by crop irrigation upstream of gage during summer months. U.S. Geological Survey satellite data-collection platform at station.
    WATER-QUALITY RECORDS
    PERIOD OF DAILY RECORD - TEMPERATURE: June 2012 to November 2019. SPECIFIC CONDUCTANCE: June 2012 to November 2019. pH: June 2012 to November 2019. DISSOLVED OXYGEN: June 2012 to November 2019. TURBIDITY: June 2012 to November 2019. NITRATE: June 2012 to November 2019.
    COOPERATION - Funding for water-quality data collection is provided by the Maryland Department of Natural Resources, the U.S. Environmental Protection Agency, and the U.S Geological Survey.
    INSTRUMENTATION - Multi-parameter water-quality monitor and ultraviolet nitrate monitor, June 2012 to November 2019.
    REMARKS - For Water Year 2015. Missing record due to periodic equipment malfunction. 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. Many data points in the 2016 WY exceeded 1000 FNU, but were kept in the record as they appeared to be reasonable when trends and site conditions such as algal blooms and accumulated sediment with the QW monitoring reach are taken into account.
    EXTREMES FOR PERIOD OF DAILY RECORD -

    WATER TEMPERATURE: Maximum, 26.6°C, June 14, 2015 Minimum, 0.6°C, Jan. 23, 2016

    SPECIFIC CONDUCTANCE: Maximum, 222 microsiemens/cm, Jan. 5, 2016 Minimum, 33 microsiemens/cm, June. 27, 2015

    pH: Maximum, 7.7 standard units, on multiple days Minimum, 6.0 standard units, June 14, 2015

    DISSOLVED OXYGEN: Maximum, 15.8 mg/l, on multiple days Minimum, 1.3 mg/l, Aug. 21, 2015

    TURBIDITY(6-Series probe): Maximum*, 990 formazin nepthelometric units, June 21, 2015; Minimum,0.0 formazin nepthelometric units on multiple days, first occurrence was Sep. 12 2017. Oct. 24, 2013 and Aug. 25, 2015 *Note: Max Turbidity recorded on 02/24/16 was 1190, but since it exceeded our highest calibration standard value, it was not included as an extreme for period of daily record.
