USGS Water-Year Summary 2023

03043810 CONEMAUGH RIVER BELOW CONEMAUGH DAM, PA

LOCATION - Lat 40°28'03", long 79°22'03" referenced to North American Datum of 1927, Indiana County, PA, Hydrologic Unit 05010007, 50 ft downstream from face of Conemaugh Dam, on right bank.

DRAINAGE AREA - 1,354 mi².

WATER-QUALITY RECORDS

PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: October 2004 to current year. pH: October 2004 to current year. WATER TEMPERATURE: October 2004 to current year.

COOPERATION - Station established and maintained by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers, Pittsburgh District.

INSTRUMENTATION - Continuous water-quality monitor interfaced with a data collection platform with 15-minute recording interval. Satellite telemetry at station.

REMARKS -

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.

Interruptions in the record are due to malfunctions of the equipment. Extremes may have been exceeded in periods of missing record during the period of record. For water year 2014, water temperature, pH and specific conductance records rated good.

For water year 2015, records for water temperature, pH, and specific conductance are rated good.

For water year 2016, records for water temperature and specific conductance are rated good. Records for pH are good, except for August 8 to September 30, which are fair, and April 24 to June 8, which are poor.

For water year 2017, records for water temperature, specific conductance, and pH are rated good.

Water year 2018, records for water temp are rated good. Records for specific conductance are rated good, except for June 16 to October September 30, which are poor. pH records are rated good, except for June 16 to September 30, which are rated poor.

For water year 2019, records for water temperature and specific conductance are rated good. Records for pH are rated fair.

Beginning water year 2020, records for water temperature, specific conductance and dissolved oxygen, and pH are no longer given qualitative ratings.
