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 2021
LOCATION - Lat 39°52'43", long 76°51'13" referenced to North American Datum of 1927, York County, PA, Hydrologic Unit 02050306, on right bank 15 ft downstream from abutments of dismantled county highway bridge on Township Route 452, 0.1 mi downstream from small left-bank tributary, 0.3 mi downstream from east boundary of Spring Grove, and 7.0 mi southwest of York.
DRAINAGE AREA - 75.5 mi².
REVISIONS HISTORY - WSP 1302: 1929-30. WSP 1502: 1932(M), 1933, 1935(M), 1940, 1942(M), 1943, 1944-46(M), 1951(M), 1955(m).
PERIOD OF RECORD - May 1929 to September 1964, November 1965 to current year. October 1962 to September 1964, November 1965 to September 1968, published as West Branch Codorus Creek at Spring Grove.
GAGE - Water-stage recorder and concrete control. Datum of gage is 430.86 ft above National Geodetic Vertical Datum of 1929. Prior to Jan 18, 1930, non-recording gage, Jan 18, 1930, to Sep 9, 1941, water-stage recorder at site 0.9 mi upstream, and Sep 10, 1941 to Sep 30, 1964, water-stage recorder at site 0.8 mi upstream, all at datum 5.64 ft higher. Nov 1 to Dec 20, 1965, non-recording gage about 40 ft downstream at unknown datum, Dec 21, 1965 to Mar 31, 1966, non-recording gage at present site and datum. Satellite telemetry at station.
COOPERATION - Records of change in lake contents and daily diversion furnished by P.H. Glatfelter Company. Station established and maintained by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers, Baltimore District.

Daily discharges include water diverted around station by waste water treatment plant of P.H. Glatfelter Company. Instantaneous data reflect actual streamflow passing the gage and do not include diverted streamflow. Flow regulated by dam on Lake Marburg (station 01574390) about 20 miles upstream. Records for water years 2014-2016 are fair except those for estimated daily discharges, which are poor. Records for water year 2017 are fair; no estimated discharges. Records for water years 2018-2020 are fair except estimated discharge, which is poor.

Discharge (w/ Glatfelter Diversion) time series created in Aquarius to calculate a total daily mean. Time series is calculated using the daily mean discharge from Codorus Creek and adding the daily mean diversions provided by Glatfelter. Glatfelter provides these diversions at the end of each water year.
