[!] During cold weather, stage and discharge values may be affected by ice at some streamgages. Streamgages experiencing ice conditions will have the discharge record temporarily disabled to prevent the display of erroneous discharge values. Display of discharge record will resume when it is determined that ice conditions are no longer present. Adjustment of data affected by ice can only be done after detailed analysis.

DRAINAGE AREA.--243 square miles.
PERIOD OF RECORD.--January 1956 to current year.
GAGE.--Water-stage recorder, crest-stage gage, and heated tipping bucket precipitation gage. Datum of gage is U.S. Army Corps of Engineers local project datum. Satellite telemetry at gage.
REMARKS.--Reservoir formed by an earthfill dam. Storage began Jan. 31, 1956. Capacity, 75,800 acre-ft between elevations 890.00 ft (sill of outlet gates) and 1,026.00 ft (crest of spillway).

The 15-minute 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.

COOPERATION.--Funding for this station is provided by the U.S. Army Corps of Engineers, Baltimore District, the Pennsylvania Department of Environmental Protection, and the U.S. Geological Survey.
This station managed by the PAWSC Williamsport Field Office.
