USGS Water-Year Summary 2023

01479820 RED CLAY CREEK NEAR KENNETT SQUARE, PA

LOCATION - Lat 39°49'00", long 75°41'31" referenced to North American Datum of 1927, Chester County, PA, Hydrologic Unit 02040205, on left bank along SR 82 (Creek Road), and 3.0 mi south of the intersection of SR 82 and U.S. Highway 1 at Kennett Square.

DRAINAGE AREA - 28.3 mi².

SURFACE-WATER RECORDS

PERIOD OF RECORD - January 1988 to current year.

GAGE - Water-stage recorder and crest-stage gage. A YSI sonde collects turbidity data at a 15-minute recording interval. Elevation of gage is 196.02 ft above National Geodetic Vertical Datum of 1929. Satellite telemetry at station.

COOPERATION - Station established and maintained by the U.S. Geological Survey. Funding for this station is provided by the Pennsylvania Department of Environmental Protection, the Delaware Geological Survey, and the U.S. Geological Survey.

REMARKS - Some regulation upstream from gage. Records rated fair except those for estimated daily discharges, which are poor.

WATER-QUALITY RECORDS

PERIOD OF DAILY RECORD - TURBIDITY: December 2015 to current year.

COOPERATION - Water-quality samples were collected as part of the Pennsylvania Department of Environmental Protection Water-Quality Network (WQN) with cooperation from the Pennsylvania Department of Environmental Protection.

REMARKS - As of October 2013, results from discrete water quality samples collected at this site are available through the U.S. Geological Survey National Water Information System web interface on the "Water Quality for the Nation" webpage. Analyses for pH, water temperature, specific conductance, and dissolved oxygen were performed on site. All other sample analyses were performed at the Pennsylvania Department of Environmental Protection laboratory in Harrisburg, Pa. Occasionally, values for filtered parameters may exceed values for the corresponding unfiltered parameter. These results are within the limits of analytical precision and methods. The reporting precision of the turbidity probe in low turbidity water is +/- 0.3 FNU, therefore the lowest reportable value, 0 FNU, does not necessarily indicate a condition of zero turbidity.

EXTREMES FOR PERIOD OF RECORD - Turbidity: Maximum 1290 FNU on June 8, 2017. Minimum: -0.1 on May 5, 2018
