Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
USGS Water-Year Summary 2024
03085000 MONONGAHELA RIVER AT BRADDOCK, PA
LOCATION - Lat 40°23'28", long 79°51'30" referenced to North American Datum of 1927, Allegheny County, PA, Hydrologic Unit 05020005, near right bank on river guide wall 300 ft upstream from dam at lock 2 at Braddock, 1,700 ft downstream from Turtle Creek, and 11.2 mi upstream of confluence with Allegheny River. Water quality sonde located on left bank, left river guide wall of lock and dam at Lat 40 23' 21.77", Long 79 51' 30.62".
DRAINAGE AREA - 7,337 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 2017 to current year.
GAGE - Water stage recorder and staff gage. Satellite telemetry at site.
COOPERATION - Station established and maintained by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers, Pittsburgh District.
REMARKS -
Record for the water year considered good.
ECOLOGICAL RECORDS
PERIOD OF RECORD - April 2002 to September 2007. (Discontinued)
REMARKS - Samples were collected using bioassessment protocols for benthic macroinvertebrates using a multiplate sampler that was placed at a depth of 1-2 ft for 5 weeks. Counts are based on a randomly-selected 100-organism (approximate) subsample.
WATER-QUALITY RECORDS
PERIOD OF RECORD -
October 1958 to September 1993. September 1994 to current year.
PERIOD OF DAILY RECORD - SPECIFIC CONDUCTANCE: January 1973 to October 1975.
WATER TEMPERATURE: January 1973 to September 1979, November 1996 to September 1998, June, 2020 to current year.
SUSPENDED SEDIMENT DISCHARGE: January 1973 to September 1979. DISSOLVED OXYGEN: June, 2020 to current year.
COOPERATION - Real time water quality station established and maintained by the U.S. Geological Survey in cooperation with the Sustainable Hydro, Braddock, LLC. Discrete 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 - Analyses for pH, water temperature, specific conductance, and dissolved oxygen were performed on site. 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.
Discharges reported are a summation of daily values of discharge from the Monongahela River at Elizabeth (station 03075070) streamgage and the Youghiogheny River at Sutersville (station 03083500) streamgage.
