USGS Water-Year Summary 2019
LOCATION - Lat 40°27'32", long 79°26'58" referenced to North American Datum of 1983, Westmoreland County, PA, Hydrologic Unit 05010008, on left bank 1,030 ft downstream from Loyalhanna Dam, 1.8 mi south of Saltsburg, and 4.7 mi upstream from confluence with Conemaugh River.
DRAINAGE AREA - 290 mi².
PERIOD OF RECORD - 1940-91, 2005-2009 (discharge measurements only), 2010 to current year.
GAGE - Water-stage recorder. Prior to Oct 1, 2004, at site 1,000 ft upstream. Datum of gage is 889.38 ft above National Geodetic Vertical Datum of 1929 (U.S. Army Corps of Engineers bench mark). Satellite telemetry at station.
COOPERATION - Station established and maintained by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers, Pittsburgh District.

Flow completely regulated by Loyalhanna Lake (station 03046850), 0.2 mi upstream, and Latrobe Reservoir, combined capacity 99,000 acre-ft. The lowest daily mean discharge for the period of daily record was the result of the gates being closed at Loyalhanna Dam. Records for water year 2015 are good except those for estimated daily discharges which are poor. Records for water year 2016 are good. Records for water year 2017 are good. Records for water year 2018 are fair, except those for estimated daily discharges, which are poor. 

PERIOD OF DAILY RECORD - WATER TEMPERATURE: October 2009 to current year.
INSTRUMENTATION - Water-temperature sensor interfaced with a data collection platform with 15-minute recording interval.

Historically, water temperatures below 0 degrees Celsius were not reported. Water temperature sensors now have the ability to accurately read water temperatures below 0 degrees Celsius. 

Cross-sectional water quality data is available upon request.

Records for water temperature in water year 2014 are fair. For water year 2015, records for water temperature are rated fair. For water year 2016, records for water temperature are rated fair.  For water year 2017, temperature records are rated poor.

For water year 2018, records for water temperature are rated poor. 



WATER TEMPERATURE: Maximum, 28.0°C, Jul 12, 2012; minimum, -0.1°C, Jan 23, 24, 31, 2011.
