  • January 22, 2018 - USGS Water Data availability during lapse in Federal funding

    Due to a lapse in Federal funding, the U.S. Geological Survey must suspend those parts of its data collection and distribution processes requiring human intervention. However, automated reporting and serving of telemetered data will continue.

    Users may note some degradation in the quality and completeness of real-time streamflow, groundwater and water-quality data from some reporting stations due to the suspension of field calibrations and adjustments, especially as high flows occur, aquatic vegetation becomes dominant, or ice forms in high altitude streams. The USGS will continue to monitor some performance aspects of its network using a skeleton workforce.

LOCATION.--Lat 42°19'50", long 73°44'38" referenced to North American Datum of 1983, Columbia County, NY, Hydrologic Unit 02020006, on right bank just downstream from Rossman Road bridge, 1.0 mi upstream from Claverack Creek, and 2.25 mi downstream from Stuyvesant Falls, in Rossman.
DRAINAGE AREA.--329 mi².
PERIOD OF RECORD.--March 1906 to June 1911, July 1911 to May 1914 (fragmentary, monthly discharge only for some periods, published in WSP 1302), July 1928 to September 1968, annual maximum only--1984, 1988-2011, August 2011 to current year.
GAGE.--Water-stage recorder and crest-stage gage. Datum of gage is 24.78 ft above NGVD of 1929. Prior to May 1914, at same site at different datum, and 1928-1962 water years, at same site at datum 1.00 ft higher.
REMARKS.--Diurnal fluctuation and considerable regulation at low and medium flow caused by power plants above station.
Water Years 2014-16: Records fair except those for estimated daily discharges, which are poor.
EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 29,800 ft³/s, Dec. 31, 1948, gage height, 20.8 ft, present datum, from floodmarks; minimum discharge not determined.
PERIOD OF DAILY RECORD1.--SUSPENDED-SEDIMENT DISCHARGE: August 2011 to February 2014 (discontinued).
REMARKS1.--Turbidity data are collected every 15 minutes using an in situ turbidity probe located near the downstream end of the central bridge pier directly across from the gage. 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, 1,070 mg/L, Aug. 28, 2011; minimum daily mean, 1 mg/L, Nov. 26, Dec. 1, 2, 2012.
SUSPENDED-SEDIMENT DISCHARGE: Maximum daily, 27,900 tons, Aug. 29, 2011; minimum daily, 0.44 tons, July 4, Aug. 9, 2012.
