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 2024
01576767 Pequea Creek near Ronks, PA
LOCATION - Lat 40°00'33", long 76°09'44" referenced to North American Datum of 1983, Lancaster County, PA, Hydrologic Unit 02050306, on right bank 100 ft downstream from South Ronks Road, 2.9 miles downstream of Watson Run, and 1.2 mi south of Ronks.
DRAINAGE AREA - 70 mi².
REVISIONS HISTORY - Revisions: Prior to September 24, 2024, the datum of gage was erroneously reported as 325 ft above National Geodetic Vertical Datum of 1929 or North American Vertical Datum of 1988 depending on source
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 2012 to present.
GAGE - Water-stage recorder, crest-stage gage, and water-quality monitor. Datum of gage 320.1 ft above North American Vertical Datum of 1988 (NAVD88) (GNSS survey). Prior to September 24, 2024, the datum of gage was erroneously reported as 325 ft above National Geodetic Vertical Datum of 1929 or NAVD88 depending on source. Satellite telemetry at station.
COOPERATION - Station established and maintained by the U.S. Geological Survey in cooperation with the U.S. Environmental Protection Agency.
REMARKS - Records for water years 2014-2016 are fair except those for estimated daily discharges, which are poor. Records for water year 2017 are good except those for estimated discharge, which is poor. Records for water years 2018-2019 are good except discharges above 200 cfs, which are fair and estimated discharge, which is poor. Records for water years 2020-2023 are fair except estimated discharge, which is poor.
WATER-QUALITY RECORDS
PERIOD OF RECORD - October 2013 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.
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.
