Hydrologic Unit 04140201, on left bank 200 ft downstream from bridge on
State Highways 31 and 48 in Baldwinsville, and 400 ft downstream from
navigation dam at Lock 24 of New York State Erie (Barge) Canal.
PERIOD OF RECORD.--
November 1949 to current year. November 1898
to December 1908, prior to construction of Erie (Barge) Canal, not
equivalent to later records at same site because of extensive
development of Erie (Barge) Canal system. January 1909 to September
1925 (gage heights only) in reports of State Engineer and
WDR NY-78-1: Drainage area.
Water-stage recorder. Datum of gage is 361.38 ft above
NGVD of 1929 (362.60 ft Erie (Barge) Canal Datum). Prior to Dec. 31,
1908, nonrecording gage at same site at different datum. Auxiliary
water-stage recorder 1,500 ft downstream from base gage at same
No estimated daily discharges. Records good except
those below 500 ft3
/s, which are poor. Discharge from
November 1898 to December 1908 determined on basis of head on dam, flow
through 10 mills nearby, lockages at Oswego Canal lock, estimated
leakage of dam, wheel gates, flumes, and penstocks; not adjusted for
inflow from Lake Erie through Erie (Barge) Canal. Discharge, from
November 1949 to September 1996, computed by using fall as determined
by auxiliary water-stage recorder. Records from October 1996 to
current, computed by using standard stage-discharge methods. Published
discharge represents the total flow at Baldwinsville and includes flow
in Erie (Barge) Canal. A large amount of natural storage and some
artificial regulation is afforded by many large lakes and the Erie
(Barge) Canal system in the river basin. Large diurnal fluctuations at
low and medium flows caused by powerplants upstream from station.
Seneca River basin receives water from Erie (Barge) Canal through Lock
32 near Pittsford. During part of year, entire flow from 45.5 mi² of
Mud Creek drainage area may be diverted from Chemung River basin into
Keuka Lake in Oswego River basin. Telephone and satellite gage-height
telemeters at station.
EXTREMES FOR PERIOD OF RECORD.--
Maximum daily discharge, 18,100
/s, Apr. 27, 1993, maximum gage height, 9.63 ft, Apr. 26,
27, 1993; minimum daily discharge, 34 ft3
/s, Sept. 17, 1985,
result of extreme regulation. Maximum and minimum instantaneous
discharges not determined.
EXTREMES OUTSIDE PERIOD OF RECORD.--
Maximum daily discharge,
