Water-Year Summary for Site 01447720

Click to hide 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 2021
01447720 TOBYHANNA CREEK NEAR BLAKESLEE, PA
LOCATION - Lat 41°05'05", long 75°36'21" referenced to North American Datum of 1927, Carbon County, PA, Hydrologic Unit 02040106, on left bank 50 ft downstream from bridge on State Highway 940, 500 ft downstream from Shingle Mill Run, and 1.5 mi southwest of Blakeslee.
DRAINAGE AREA - 118 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 1961 to current year.
GAGE - Water-stage recorder, crest-stage gage, water-quality monitor, and weighing bucket precipitation gage. Datum of gage is 1,511.23 ft above National Geodetic Vertical Datum of 1929. Prior to Jan. 16, 1962, non-recording gage at site 50 ft upstream at same datum. Satellite and landline telemetry at station.
COOPERATION - Station established and maintained by the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers, Philadelphia District, and the Pennsylvania Department of Environmental Protection.
REMARKS - Discharges affected by power generation at Pocono Lake about 5.0 mi upstream since 1985 and minor diversion from Tunkhannock Creek Basin into Wild Creek Basin. Records are good except those for estimated discharge, which are poor. 
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of Aug. 19, 1955, reached a stage of 19.41 ft, from floodmark, discharge, 35,300 ft³/s, determined by slope-area measurement.
WATER-QUALITY RECORDS
PERIOD OF RECORD - Water years 1930 to 1982, 2002 to current year.
PERIOD OF DAILY RECORD - WATER TEMPERATURE: Water year 1980 to Sep 30, 2004. Oct 1, 2017 to current year.
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.

Cross-sectional water temperature data is available upon request. 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. Subsequent to water year 2015, water temperatures below 0 degrees Celsius are reported. 
EXTREMES FOR PERIOD OF DAILY RECORD - Water Temperature: Maximum, 28.5° C, Jul 5, 6, 1999; minimum -0.2° C, Mar 7, 8, 2019.
