  • UPDATE, 11/9: As of November 8, the USGS has successfully restored all of the operational gages that stopped transmitting due to an issue with the satellite telemetry system that records and transmits data. The USGS will now focus on restoring other equipment that experienced the telemetry issues, including about 85 rapid deployment gages that are used periodically for emergency response. Read more

USGS Water-Year Summary 2018
LOCATION - Lat 41°55'05.3", long 73°58'54.2" referenced to North American Datum of 1983, Ulster County, NY, Hydrologic Unit 02020007, on left bank at State Highway 9W bridge and 1.1 mi above mouth, at Rondout.
DRAINAGE AREA - 1,185 mi².
PERIOD OF RECORD - Miscellaneous measurements--2008, 2011. March 2011 to March 2015 (discontinued).
GAGE - Water-stage recorder and acoustic velocity meter. Datum of gage is 3.45 ft below NGVD of 1929.
REMARKS - Flow at this site is affected by astronomical tides.
Water Years 2014-15: Records good.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 59,700 ft³/s, Aug. 28, 2011, gage height, 11.86 ft; maximum gage height, 13.42 ft, Oct. 30, 2012; minimum discharge not determined; minimum gage height, 0.02 ft, Feb. 26, 2012.
PERIOD OF DAILY RECORD - SUSPENDED-SEDIMENT DISCHARGE: March 2011 to March 2015 (discontinued).
REMARKS - Turbidity data are collected every 6 minutes using an in situ turbidity probe located at the automatic sampler intake tubing. Daily suspended-sediment load and concentration are derived from a regression equation relating turbidity to suspended-sediment concentration. A negative load indicates the net movement of suspended sediment was upstream for that day.
EXTREMES FOR PERIOD OF DAILY RECORD - SUSPENDED-SEDIMENT CONCENTRATION: Maximum daily mean, 518 mg/L, Aug. 28, 2011; minimum daily mean, 1 mg/L, Nov. 26, 2013. SUSPENDED-SEDIMENT DISCHARGE: Maximum daily, 70,700 tons, Aug. 28, 2011; minimum daily, -7.5 tons, July 21, 2013.
