USGS Water-Year Summary 2024

01447500 LEHIGH RIVER AT STODDARTSVILLE, PA

LOCATION - Lat 41°07'49", long 75°37'33" referenced to North American Datum of 1927, Monroe County, PA, Hydrologic Unit 02040106, on left bank 75 ft upstream from bridge on State Highway 115, at Stoddartsville, 1.9 mi upstream from Tobyhanna Creek, and 4.0 mi southwest of Thornhurst.

DRAINAGE AREA - 91.7 mi².

REVISIONS HISTORY -

WSP 1382: 1947, 1951; WDR-US-2012: 2010(M).

Peak gage height and discharge for the 2014 WY was revised on September 30, 2022 due to the incorrect values being previously entered.

SURFACE-WATER RECORDS

PERIOD OF RECORD - October 1943 to current year.

GAGE - Water-stage recorder, crest-stage gage, water-quality monitor, and weighing bucket precipitation gage. Datum of gage is 1463.16 ft above North American Vertical Datum of 1988 from benchmark. Prior to Oct. 1, 1946, non-recording gage at site 350 ft downstream at datum 2.14 ft lower. Prior to June 24, 2024, the datum of gage was reported as 1,463.81 ft above National Geodetic Vertical Datum of 1929. Satellite and landline 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, Philadelphia District and the Pennsylvania Department of Environmental Protection.

REMARKS - Occasional pumping and return from stone quarry located upstream of gage. Records are good except those for estimated discharges, which are poor.

EXTREMES OUTSIDE PERIOD OF RECORD - Flood of May 22, 1942, reached a stage of 12.03 ft, from floodmark, present site and datum, discharge, 15,700 ft³/s.

WATER-QUALITY RECORDS

PERIOD OF RECORD - Water years 1926 to 1982; April 2002 to current year.

PERIOD OF DAILY RECORD - WATER TEMPERATURE: Oct 1980 to Sep 2004. Oct 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. Some values for filtered parameters 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. Beginning in water year 2019, water quality records are not rated as "excellent", "good", "fair", or "poor".

EXTREMES FOR PERIOD OF DAILY RECORD - Water Temperature: Maximum, 31.5° C, Jul 6, 1999; minimum -0.1°C, many days during winter periods.
