> Site Information
LOCATION.--Lat 42°13'23.7", long 73°53'07.5" referenced to North American Datum of 1983, Greene County, NY, Hydrologic Unit 02020006, on left bank 0.3 mi downstream of Kaaterskill Creek, and 1.10 mi upstream of State Highway 9W bridge in Catskill.
DRAINAGE AREA.--405 mi².
PERIOD OF RECORD.--Miscellaneous discharge measurements, water years 2008, 2011. March 2011 to March 2015 (discontinued).
REVISIONS HISTORY.--2011-13: Daily suspended-sediment discharge and concentration.
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 3.96 ft above NGVD of 1929. Auxiliary water-stage recorder and crest-stage gage, 0.2 mi downstream from base gage at datum 0.90 ft below NGVD of 1929.
REMARKS.--Considerable regulation at low to medium flow at times caused by powerplant upstream from station.
Water Year 2014: Records poor except those for Sept. 8 to Sept. 30, which are good. Water Year 2015: Records good except those for estimated daily discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, about 64,000 ft³/s, Aug. 28, 2011, gage height, 27.42 ft, from floodmarks, from runoff comparisons of peak flow with nearby stations; minimum discharge not determined.
PERIOD OF DAILY RECORD1.--SUSPENDED-SEDIMENT DISCHARGE: March 2011 to March 2015 (discontinued).
REMARKS1.--Turbidity data are collected every 15 minutes using an in situ turbidity probe located 30 ft upstream of the automatic sampler intake tubing. Daily suspended-sediment load and concentration are derived from a regression equation relating turbidity to suspended-sediment concentration.
EXTREMES FOR PERIOD OF DAILY RECORD1.--SUSPENDED-SEDIMENT CONCENTRATION: Maximum daily mean, about 4,090 mg/L, Aug. 28, 2011; minimum daily mean, <0.5 mg/L, Dec. 1, 2012.
SUSPENDED-SEDIMENT DISCHARGE: Maximum daily, about 487,000 tons, Aug. 28, 2011; minimum daily, 0.09 tons, Sept. 26, 27, 2014, but may have been less on Dec. 1, 2012.
