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 2023
01478185 Middle Branch White Clay Creek near West Grove,PA
LOCATION - Lat 39°49'57.3", long 75°50'42.3" referenced to North American Datum of 1983, Chester County, PA, Hydrologic Unit 02040205,
DRAINAGE AREA - 4.68 mi².  
REVISIONS HISTORY - Prior to March 14, 2022, the datum of gage was reported as 406 ft above North American Vertical Datum of 1988 (NAVD88)
SURFACE-WATER RECORDS
PERIOD OF RECORD - February 2020 to current year.
GAGE -

Water-stage recorder, crest-stage gage, and water quality monitor. Datum of gage is 396.60 ft. above North American Vertical Datum of 1988, from single-base GNSS rapid static survey.  Previous to March 14, 2022, the datum of gage was erroneously reported as 406 ft above North American Vertical Datum of 1988.

COOPERATION - The station is maintained by the U.S. Geological Survey with funding provided by the U.S. Geological Survey Next Generation Water Observing System(NGWOS).
WATER-QUALITY RECORDS
PERIOD OF RECORD - Water Temperature and Specific Conductance, Feb 2020 to current year. Turbidity, July 2020 to current year.
COOPERATION - The station is maintained by the U.S. Geological Survey with funding provided by the U.S. Geological Survey Next Generation Water Observing System(NGWOS).
INSTRUMENTATION - Temperature, specific conductance, and turbidity are collected on a 15-minute interval from a water-quality sonde interfaced with site telemetry.
REMARKS - The reporting precision of the turbidity probe in low turbidity water is +/-0.3 FNU. The lowest reportable value, 0 FNU, is subject to this error and does not necessarily indicate a condition of zero turbidity. Turbidity values greater than 1300 FNU are beyond the specification of the sensor and are considered unreliable. Interruptions in the record were due to malfunctions of the equipment.
EXTREMES FOR PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: Maximum, 399 microsiemens/cm, first occurence Sept. 25, 2021; minimum, 44 microsiemens/cm, Sept. 01, 2021. WATER TEMPERATURE: Maximum, 25.6°C, first on Jun. 30, 2021 and multiple occasions; minimum afterward, 0°C, first on Dec. 12, 2020 and multiple occasions afterward. TURBIDITY: Maximum 1480 FNU, Feb 28, 2021; minimum, <0.3 FNU, many days.
