[!] Over the next year, the USGS Pennsylvania Water Science Center will be updating the geodetic vertical elevation (gage datum) for many locations. Click HERE for additional information including a current list of streamgages with upcoming datum changes. This update in gage datum does not affect the location of the streamgage, nor the observed local gage height or discharge recorded at the streamgage.

03044810 LINN RUN AT LINN RUN STATE PARK NEAR RECTOR, PA
LOCATION - Lat 40°10'08", long 79°14'02" referenced to North American Datum of 1983, Westmoreland County, PA, Hydrologic Unit 05010008, on left bank, 8 ft downstream of Adams Falls Picnic Area access bridge, 0.7 mi downstream from Rock Run, 2.6 mi upstream from mouth at Loyalhanna Creek, and 5.2 mi south of Ligonier.
DRAINAGE AREA - 8 mi².
REVISIONS HISTORY - Revisions: Prior to December 21, 2023, the datum of gage was erroneously reported as 1.550 ft above National Geodetic Vertical Datum of 1929.
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 2006 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 1,545.4 ft above North American Vertical Datum of 1988 from rapid-static GNSS survey.  Prior to December 21, 2023, the datum of gage was erroneously reported as 1,550 ft above National Geodetic Vertical Datum of 1929.  Satellite telemetry at station.
COOPERATION - Station established and maintained by the U.S. Geological Survey in cooperation with the Department of Conservation and Natural Resources, Pennsylvania Topographic and Geologic Survey.
REMARKS -

Records are poor.

Between June 18, 2020 and October 14th, 2020, the gage was temporarily moved downstream due to bridge construction at the site. This resulted in a temporary adjustment to the datum between these dates in order to maintain a positive gage height. All changes to gage height and the datum have been reverted to original conditions as of October 14th, 2020.
