PERIOD OF RECORD.--
October 1939 to current year.
WDR NY-82-1: 1981(average discharge). WDR
NY-90-1: Drainage area.
Water-stage recorder and crest-stage gage. Datum of gage
is 507.98 ft above NGVD of 1929 and 507.44 ft above NAVD of 1988.
Flow regulated to some extent by Blenheim-Gilboa
Pumped Storage Project about 37 mi upstream. Entire flow, runoff from
315 mi², except for periods of spill, diverted from Schoharie Reservoir
through Shandaken Tunnel into Esopus Creek upstream from Ashokan
Reservoir for water supply of City of New York. For days of reservoir
outflow greater than 10 ft³/s, see station 01350101.
Water Year 2014: Records fair except those for estimated daily
discharges, which are poor. Water Year 2015: Records good except those
for estimated daily discharges, which are poor. Water Years 2016-18:
Records good except those for estimated daily discharges, which are
EXTREMES FOR PERIOD OF RECORD.--
Maximum discharge, 128,000
ft³/s, Aug. 29, 2011, gage height, 17.46 ft, from floodmark in gage
house, from rating curve extended above 75,000 ft³/s on basis of runoff
comparison of peak flows from contracted-opening and flow-over-road
measurement and slope-area measurement at site 3.3 mi upstream; minimum
discharge, 2.4 ft³/s, Sept. 24, 25, 1964, gage height, 0.30 ft.
EXTREMES OUTSIDE PERIOD OF RECORD.--
Floods of March 1936 and
September 1938 reached stages of 10.5 and 10.2 ft, respectively, from
information provided by local resident. However, flood of October 1903
is known to have reached a higher stage than the 1936 or 1938
PERIOD OF DAILY RECORD1.--
DISCHARGE: October 2012 to current year.
Turbidity data are collected every 15
minutes using an in-situ turbidity probe located in the same pipe
adjacent to the automatic sampler intake tubing. Daily
suspended-sediment load and concentration are derived from a regression
equation relating turbidity to suspended-sediment concentration.
