ICE EFFECTS ON STREAMFLOW

The formation of ice on rivers can cause discharge values to appear unusually high. Display of these erroneous discharge data may result in improper assessment of flow conditions and misuse of the data. For this reason, display of discharge values for streams significantly affected by ice may be disabled from view. Display of discharge data will resume when ice conditions are no longer present. Discharge values for streams minimally affected by ice will continue to be displayed. Flows for streams with these conditions appear to increase during the night and decrease to near-base-line conditions around midday. To estimate the correct discharge for these streams, use the flow rate that corresponds to the bottom of the discharge curve, rather than the peak that corresponds to the top of the curve. Note that this method of estimation is possible only when no surface runoff is occurring. Daily mean discharges for periods of both significant and minimal ice-effect will be estimated and published in the Annual Water-Data Report for the water year in which they occurred.

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

LOCATION--Lat 41° 51'32", long 71° 29'16", Providence County, Hydrologic Unit 01090004, on right bank 75 ft downstream from bridge on U.S. Highway 44 at Centerdale and 6.5 mi upstream from mouth.
DRAINAGE AREA--38.3 mi2.
PERIOD OF RECORD--Discharge: July 1941 to current year. Water-quality records: Water years 1955-56.
GAGE--Data Collection Platform with satellite telemeter. Elevation of gage is 94.19 ft above NAVD 1988, estimated from topographic map. Datum of gage previously reported as 95 ft above NGVD 1929, estimated from topographic map.
REMARKS--Some regulation by reservoirs upstream; regulation greater prior to 1956. Discharge figures prior to 1966 included leakage around station through bypass canal; leakage negligible subsequently.
COOPERATION BY--Rhode Island Department of Environmental Management
