Click to hidestation-specific text


ATTENTION!!! Please be aware that the sharp rises and drops in the graphs displayed for some of the Allegheny River gages are being caused by hydroelectric power producers passing relatively large amounts of streamflow.

LOCATION.--Lat 40`49'13", long 79`31'54", Armstrong County, Hydrologic Unit 05010006, on right bank 600 ft upstream from dam at lock 7 at Kittanning, 5.7 mi upstream from Crooked Creek, 9.7 mi downstream from Mahoning Creek, and at mile 45.8.
DRAINAGE AREA.--8,973 square miles.
PERIOD OF RECORD.--August 1904 to September 1928, October 1934 to current year. Monthly discharge only for some periods, published in WSP 1305.
GAGE.--Water-stage recorder, heated tipping bucket precipitation gage, and concrete dam control. Datum of gage is 772.8 ft above North American Vertical Datum of 1988. Prior to Sept. 30, 1928, non-recording gage at site 4,000 ft downstream at different datum. Oct. 1, 1934 to Apr. 19, 1939, non-recording gage, Apr. 20, 1939 to Sept. 27, 1990, water-stage recorder at present site at different datum. Prior to November 2, 2023, the datum of gage was reported as 773.40 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 the operation of 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.--Sharp rises and drops in discharge during periods of low flow may be caused by hydroelectric power production. Flow regulated since 1924 by Piney Reservoir, since December 1940 by Tionesta Lake (station 03019500), since June 1941 by Mahoning Creek Lake (station 03035500), since November 1949 by Chautauqua Lake, since June 1952 by East Branch Clarion River Lake (station 03027000), since October 1965 by Allegheny Reservoir (station 03012520), since July 1970 by Union City Reservoir (station 03021518), and since January 1974 by Woodcock Creek Lake (station 03022550).
The 15-minute 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.

Supplied by NWS: Action stage-17 ft; Flood stage-21 ft; Moderate flood stage-22 ft; Major flood stage-23 ft.
This station managed by the PAWSC Pittsburgh Field Office.
