Due to a lapse in Federal funding, the U.S. Geological Survey must suspend those parts of its data collection and distribution processes requiring human intervention. However, automated reporting and serving of telemetered data will continue.
Users may note some degradation in the quality and completeness of real-time streamflow, groundwater and water-quality data from some reporting stations due to the suspension of field calibrations and adjustments, especially as high flows occur, aquatic vegetation becomes dominant, or ice forms in high altitude streams. The USGS will continue to monitor some performance aspects of its network using a skeleton workforce.
LOCATION.--Lat 39°45'46.1", long 75°38'11.4", New Castle County, Hydrologic Unit 02040205, on right bank 12 ft upstream from bridge on State Highway 48, 0.3 mi south of Wooddale, 2.3 mi north of Marshallton, and 4.9 mi upstream from mouth. DRAINAGE AREA.--47.0 mi2. PERIOD OF RECORD.--April 1943 to current year. REVISED RECORDS.-- WSP 1141: 1948. WSP 1272: 1951(m). WSP 1432: 1944(M), 1945, 1946(M), 1948, 1949(M). WSP 2102: 1960(M), 1964(M), 1966-67(M). WDR MD-DE-DC-04-1: 2003 (P). WRD-US-2012: 2003 (September monthly mean). GAGE.--Water-stage recorder, concrete control, and crest-stage gage. Datum of gage is 80.34 ft above North American Vertical Datum of 1988. Prior to Sept. 21, 1950, nonrecording gage at site 10 ft downstream at same gage datum. REMARKS.-- Low flows augmented at times by inflow from Hoopes Reservoir located 1.7 miles upstream from gage on unnamed tributary to Red Clay Creek, capacity 2,000,000,000 gal. Water from Brandywine Creek is pumped into Hoopes Reservoir and is released into Red Clay Creek during periods of low flow. Water from Red Clay Creek is used for municipal supply. U.S. Geological Survey satellite data-collection platform at station. Water-quality records for some prior periods have been collected at this location. EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 15,600 ft3/s, Sep. 15, 2003, gage height, 17.62 ft; minimum discharge, 2.90 ft3/s, Sept. 4, 1966. COOPERATION.--Funding for the operation of this station is provided by the Delaware Geological Survey and the U. S. Geological Survey. CRITICAL LEVELS.--Bankfull stage: 5.5 ft, Flood stage: 7.0 ft, information provided by the National Weather Service.
