Station gage imageSTATION.--03072655 MONONGAHELA RIVER NEAR MASONTOWN, PA
LOCATION.--Lat 39`49'30", long 79`55'23", Greene County, Hydrologic Unit 05020005, on left bank, 84 ft upstream from Lock and Dam at Grays Landing, 0.9 mi upstream from Masontown, 1.2 mi upstream from Whitely Creek, 5.3 mi downstream from Dunkard Creek, 7.6 mi downstream from Cheat River, at mile 81.9.
DRAINAGE AREA.--4,440 square miles.
PERIOD OF RECORD.--October 1938 to current year.
GAGE.--Water-stage recorder, heated tipping bucket precipitation gage and concrete dam control. Datum of gage is 769.00 ft above National Geodatic Vertical Datum of 1929 (U.S. Army Corps of Engineers bench mark). Prior to Nov. 8, 1990, at datum 1.45 lower. Satellite 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, Pittsburgh District, the Pennsylvania Department of Environmental Protection and the U.S. Geological Survey.
REMARKS.--Flow regulated by Lake Lynn 11 mi upstream, since May 1938 by Tygart Lake (station 03055500) 69 mi upstream and by Stonewall Jackson Lake 120.6 mi upstream, combined capacity, 432,000 acre-ft.
The 1-hour precipitation data for this station are temporary and will only be displayed for 120 days. Time series of 1-hour or cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once a year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.

GAGE HEIGHTS OF IMPORTANCE.-
Supplied by NWS: Action stage-15 ft; Flood stage-21 ft; Moderate flood stage-25 ft; Major flood stage-27 ft.
