USGS 01118500 PAWCATUCK RIVER AT WESTERLY, RI

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

LOCATION--Lat 41°23’01", long 71°50’01", Washington County, Hydrologic Unit 01090005, on left bank at Westerly, 2.1 mi downstream from Shunock River.
DRAINAGE AREA--295 mi2.
PERIOD OF RECORD--Discharge: November 1940 to current year.
Water-quality records: Water years 1953, 1963, 1976–2002.
REVISED RECORDS--WSP 1051: drainage area.
GAGE--Data Collection Platform with satellite telemeter. Datum of gage is 2.68 ft below NAVD 1988; 1.76 ft below NGVD 1929.
REMARKS--Records good except those for estimated daily discharge, which are fair. Many days are adjusted for tidal backwater, which lasts as much as 4 hours during times of high tide. Diurnal fluctuation at low flow prior to 1962 by mills upstream; regulation much greater prior to 1958. Diversion upstream for municipal supply of Westerly.
COOPERATION BY--Rhode Island Water Resources Board
