PERIOD OF RECORD.--
Occasional discharge measurements water years
1941, 1968-69. October 1974 to current year.
WDR NY-78-1: 1976, 1977 (M). WDR NY-83-3: 1982
Water-stage recorder. Datum of gage is 900.00 ft above
NGVD of 1929.
Records good except those for estimated daily
discharges, which are fair. High flows significantly regulated by
upstream reservoirs. During each year a large part of flow from 45.5
of drainage area is diverted upstream from Lake Lamoka
on Mud Creek, an upstream tributary, into Keuka Lake (Oswego River
basin) for power development. Telephone and satellite gage-height
telemeters at station.
EXTREMES FOR PERIOD OF RECORD.--
Maximum discharge, since
construction of Tioga Reservoir in 1979, about 61,000 ft3
Jan. 19, 1996; minimum discharge, 95 ft3
/s, Sept. 9, 10, 23,
24, 1991, gage height, 14.30 ft.
EXTREMES OUTSIDE PERIOD OF RECORD.--
Flood of June 23, 1972,
reached a stage of 40.71 ft, from floodmark; discharge 228,000
/s, from peak flows determined at upstream and downstream
stations adjusted for drainage area and channel storage.
EXTREMES FOR PERIOD PRIOR TO REGULATION.--
prior to construction of Tioga Reservoir in 1979, 127,000
/s, Sept. 26, 1975, gage height, 32.46 ft; minimum
discharge, 210 ft3
