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).

FLOOD BY-PASS SIPHON INFORMATION--Whitman's Pond Dam contains four siphon openings which are designed to by-pass high flows around the Whitman's Pond Dam fish ladder directly to the lower Iron Hill Pond. The four siphon openings located at Iron Hill Pond Dam are designed to by-pass flood flows around the Iron Hill Pond Dam fish ladder directly to the flood by-pass system that discharges flood flows to the inter-tidal zone downstream of Jackson Square. The following list shows the bottom elevations for the Whitman's Pond Dam siphon openings. Siphon Unit 2 is the first unit to by-pass flood flows to Iron Hill Pond and is at the same elevation as the spillway.

Whitman's Pond Dam--flows by-pass Whitman's Pond fish ladder when Whitman's Pond elevation exceeds the following siphon inlet elevations (Town of Weymouth Datum, in feet):

Siphon Unit 2 72.47
Siphon Unit 3 72.57
