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.

03080000 LAUREL HILL CREEK AT URSINA, PA
LOCATION - Lat 39°49'13", long 79°19'18" referenced to North American Datum of 1927, Somerset County, PA, Hydrologic Unit 05020006, on right bank 500 ft downstream from bridge on State Highway 281 at Ursina, and 2.7 mi upstream from mouth.
DRAINAGE AREA - 121 mi².
REVISIONS HISTORY -
WSP 743: Drainage area. WSP 893: 1919-21, 1932-34. WSP 1305: 1922-31. WSP 1435: 1919-20. WSP 1625: 1932 (M).
Revisions: Discharge for the period of 6/8/2020 - 6/24/2020 was revised on 1/20/2021. Erroneous gage height data was deleted and the discharge was estimated
Revisions: Gage height and discharge for the period of 6/25/2020 - 10/6/2020 were revised on 1/28/2021 due to deletion of erroneous gage height data and estimation of missing discharge values.
Revisions: Datum of gage was reported as 1,335.26 ft above National Geodetic Vertical Datum of 1929 prior to January 4, 2024.
SURFACE-WATER RECORDS
PERIOD OF RECORD - August to September 1913 (gage heights and discharge measurements only), October 1918 to current year. Monthly discharge only for some periods, published in WSP 1305. October 1913 to September 1918 (gage heights and discharge measurements only) in reports of Water Supply Commission of Pennsylvania.
GAGE - Water-stage recorder and masonry control. Datum of gage is 1,334.3 ft above North American Vertical Datum of 1988. Prior to July 18, 1939, non-recording gage at bridge 0.5 mi downstream at datum 6.20 ft lower. Prior to January 4, 2023, the datum of gage was erroneously reported as 1,335.26 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 U.S. Army Corps of Engineers, Pittsburgh District, the Pennsylvania Department of Environmental Protection, and the U.S. Geological Survey.
REMARKS - Record good except those for estimated daily discharges, which are poor.
WATER-QUALITY RECORDS
PERIOD OF RECORD - June 2007 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.
