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
