    Click to hidestation-specific text

    LOCATION--Lat 42° 00’22", long 71° 30’13", Providence County, Hydrologic Unit 01090003, on right bank 50 ft upstream from Peters River pressure conduit at Woonsocket. Records include flow of Peters River.
    DRAINAGE AREA--416 mi2.
    PERIOD OF RECORD--Discharge: February 1929 to current year.
    Water-quality records: Water years 1952–53, 1957–58, 1962–67.
    REVISED RECORDS--WSP 756: drainage area. WSP 781: 1931(M). WSP 871: 1938. WSP 1051: 1931.
    GAGE--Data Collection Platform with satellite telemeter. Datum of gage is 107.42 ft above sea level.
    REMARKS--Flow regulated by powerplants, by West Hill Reservoir since May 1961, and by other reservoirs upstream. Extremes and figures of daily discharge include flow diverted from Nashua River basin and, at times since January 1966, from Quabbin Reservoir for supply of Worcester, MA, and, prior to July 1964, flow diverted around station in Hamlet Trench.
    COOPERATION BY--Ocean State Power

    ICE EFFECTS ON STREAMFLOW During winter, ice formation in streams can cause stage and corresponding discharge values to appear higher than expected during periods of no precipitation. Ice effects from partial ice cover or shore ice may be minor, where stage and discharge appear to increase at night and decrease to base-line conditions around midday for one or more days. Major ice effects from complete ice cover appear as constantly increasing stage and discharge over several days during prolonged cold periods. Stage and discharge values for streams experiencing minor ice effects will continue to be displayed on the web to enable the user to estimate the approximate base-line discharges. Note that this method of estimation should only be used when no runoff occurs. During periods of major ice effects, display of discharge data on the web will be temporarily discontinued to prevent misuse of erroneous discharge data. The discharge record will resume when it is determined that ice conditions are no longer present. Display of stage data during periods of minor and major ice effects will continue to be displayed on the web. Daily mean discharges will be estimated for all periods of ice-effected discharges.
