Discontinuation of Streamgaging Stations

Discontinuation of Plum Island River at TPK Bridge at Plum Island, MA Streamgaging Station

The streamgaging station, Plum Island River at Plum Island, MA (42475200491701), was discontinued October 1, 2017 due to insufficient funds. This station has operated continuously since August 2015 and has provided river stage and discharge data to numerous Federal, State, and local water-management agencies to monitor and manage water resources.

If any Federal, State or local agencies are interested in providing the additional funds needed to continue operation of this streamflow gaging station, please contact Richard Verdi, Chief of Hydrologic Surveillance, New England Water Science Center (508-490-5064).

LOCATION--Lat 42o24'39", long 71o47'30", Worcester County, Hydrologic Unit 01070004, on left bank at downstream side of bridge on Muddy Pond Road, 1.5 mi upstream from mouth and 2.5 mi southwest of Sterling.
DRAINAGE AREA--29.1 mi2.

PERIOD OF RECORD--Low-flow partial record measurements in water years 1971-73, 1991-93. Continuous stage data recorder April 1994 to current year.
GAGE--Data Collection Platform with telephone telemeter. Elevation of gage is 400 ft above National Geodetic Vertical Datum of 1929, from topographic map. Telephone gage-height telemeter at station.
REMARKS--Stage-discharge relation affected by seasonal backwater from aquatic vegetation and occasional backwater from beaver dams. Adjustments for backwater are included in the computed record.

Daily and unit values precipitation data are calibrated and quality assured prior to publication by the Massachusetts-Rhode Island Water Science Center. Data are available upon request.

PERIOD OF RECORD--Water temperature and specific conductance, April 1998 to current year; precipitation October 1998 to current year.
INSTRUMENTATION--Water temperature and specific conductance monitor and heated tipping-bucket precipitation gage.

This gage is monitored in cooperation with the Massachusetts Department of Conservation and Recreation, Division of Water Supply Protection, Office of Watershed Management, with funding from the Massachusetts Water Resources Authority .
