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.

SURFACE-WATER RECORDS
PERIOD OF RECORD - April 1943 to current year.
GAGE - Water-stage recorder, concrete control, and crest-stage gage. Datum of gage is 80.31 ft above North American Vertical Datum of 1988 and 81.46 ft above National Geodetic Vertical Datum of 1929. Prior to Sept. 21, 1950, nonrecording gage at site 10 ft downstream at same gage datum.
REMARKS - Water Year 2024: Records good, except those above 1,700 ft³/s and those for estimated discharges, which are poor.
Water Year 2023: Records good, except those above 1,700 ft³/s, which are poor. No estimated discharges.
Water Year 2022: Records good, except those above 1,700 ft³/s and those for estimated discharges, which are poor.
Water Year 2021: Records good, except those above 1,700 ft³/s, which are poor.
Water Year 2020: Records good, except those above 1,700 ft³/s and those for estimated discharges, which are poor.
Water Years 2017-2019: Records good, except those above 1,000 ft³/s and those for estimated discharges, which are poor.
Water Year 2016: Records good, except those above 1,000 ft³/s and those for estimated daily discharges, which are poor.
Water Year 2015: Records good below 400 ft³/s and fair above, except those above 1,200 ft³/s and those for estimated daily discharges, which are poor.
Water Year 2014: Records good below 120 ft³/s and fair above, except those above 1,500 ft³/s and those for estimated daily discharges, which are poor.
Water Year 2013 and prior years’ accuracy statements can be found in Annual Water Data Reports.
Low flows augmented at times by inflow from Hoopes Reservoir located 1.7 mi 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.
