[!] 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.

Funding for this site is provided by:


LOCATION.--Lat 41`50'29", long 79`00'44", Warren County, Hydrologic Unit 05010001.
DRAINAGE AREA.--2,180 square miles.
PERIOD OF RECORD.--1936-91, 2005-2009 (discharge measurements only), 2010 to current year. Published as "near Kinzua" (Station 03012500) prior to October 1968, and as "at Warren" (Station 03012600) October 1968 to September 1972.
GAGE.--Water-stage recorder and heated tipping bucket precipitation gage. Elevation of gage is 1,192.8 ft above North American Vertical Datum of 1988. Prior to April 4, 2023, the datum of gage was erroneously reported as 1,192.55 ft above National Geodetic Vertical Datum of 1929.
COOPERATION.--Station established and maintained by the U.S. Geological Survey. Funding for the operation of this station is provided by the U.S. Army Corps of Engineers, Pittsburgh District.
REMARKS.--Flow regulated since October 1965 by Allegheny Reservoir (station 03012520), 0.5 mile upstream.Satellite telemetery at station.
The 1-hour precipitation data for this station are temporary and will only be displayed for 120 days. Time series of 1-hour or cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once a year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
This station managed by the PAWSC Pittsburgh Field Office.
