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).

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

LOCATION--Middlesex County, Hydrologic Unit 01090001, on right bank, 50 ft downstream of culvert at Winter Street, 300 ft downstream of gate house outlet from Cambridge Reservoir, and 1.3 mi north of Kendal Green.
DRAINAGE AREA--6.86 mi2.
PERIOD OF RECORD--July 1997 to current year.
GAGE--Data Collection Platform, water-temperature and specific conductance monitor, air temperature monitor, and a heated tipping-bucket precipitation gage equipped with a wind shield. Elevation of gage is 150 ft above sea level (from topographic map). Telephone telemeter at station. Datum of gage is referenced to the City of Cambridge datum, subtract 10.84 feet to elevations to adjust to National Geodetic Vertical Datum of 1929. Dissolved chloride and sodium concentrations estimated from specific conductance measurements using the regression technique described in Smith 2013.
REMARKS--Flow affected by regulation of dam 300 ft upstream at outflow of Cambridge Reservoir.
COOPERATION BY--Cambridge Water Department

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.
