USGS Water-Year Summary 2019
03036500 ALLEGHENY RIVER AT KITTANNING, PA
LOCATION - Lat 40°49'13", long 79°31'54" referenced to North American Datum of 1927, Armstrong County, PA, Hydrologic Unit 05010006, on right bank 600 ft upstream from dam at lock 7, 3,000 ft upstream from bridge on SR 1038 at Kittanning, 5.7 mi upstream from Crooked Creek, and 9.7 mi downstream from Mahoning Creek, at river mile 45.8.
DRAINAGE AREA - 8,973 mi².
REVISIONS HISTORY - WSP 873: Drainage area. WSP 1305: 1906 (M), 1914, 1925. WSP 1435: 1936-37, 1939.
SURFACE-WATER RECORDS
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 and concrete dam control. Datum of gage is 773.40 ft above National Geodetic Vertical Datum of 1929 (U.S. Army Corps of Engineers bench mark). Prior to Sep 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 Sep 27, 1990, water-stage recorder at present site at different datum. 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). Records for water year 2015 are good except those for estimated daily discharges, which are poor. Records for water year 2016 are good except those for estimated daily discharges, which are poor.  Records for water year 2017 are good except those for estimated discharges, which are poor. Records for water year 2018 are good except those for estimated discharges, which are poor.

WATER-QUALITY RECORDS
PERIOD OF RECORD - April 2002 to current year.
PERIOD OF DAILY RECORD - WATER TEMPERATURE: May 2009 to September 2009. SPECIFIC CONDUCTANCE: May 2009 to September 2009. pH: May 2009 to September 2009. DISSOLVED OXYGEN: May 2009 to September 2009.
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.
