DRAINAGE AREA.--446 mi2. PERIOD OF RECORD.--July 1976 to current year. GAGE.--Water-stage recorder. Datum of gage is 990.43 ft above National Geodetic Vertical Datum of 1929. GAGE HEIGHTS OF IMPORTANCE.-- Supplied by USGS: Maximum recordable gage height (stage sensor operational limit) - 28.2 ft; Data transmitter operational limit - 29.6 ft; Supplied by NWS: Action stage-13 ft; Flood stage-15 ft, the left or west bank overflows-some road closures;few homes affected; Moderate flood stage-17 ft, the right or east bank overflows-several roads are closed;a number of homes on both banks affected; Major flood stage-20 ft, widespread flooding on both banks. A number of roads are closed. Much of Tioga Junction affected by high water. EXTREMES OUTSIDE PERIOD OF RECORD.--Flood of September 1975 reached a stage of about 22.1 ft, from floodmarks, discharge, about 48,000 ft3/s. COOPERATION.--Funding for the operation of this station is provided by the U.S. Army Corps of Engineers, Baltimore District and the U.S. Geological Survey.
