Town Brook Dam Removal
Scope: The Town of Plymouth Department of Public Works Environmental Management Division is completing design and entering the permitting phase for the Off Billington Street and Plymco Dams located on Town Brook.
This Feasibility study (below) assessed the current conditions of the structures, public safety, environmental and cost issues associated with repairing or removing these structures. It includes survey, HEC-RAS modeling, flow and flood analysis, fish passage analysis and sediment contamination review. It provides cost estimates with each alternative to the Town for final decision-making.
Partners: Town of Plymouth Planning Department, NOAA Restoration Center, Massachusetts Riverways Program, Massachusetts Division of Marine Fisheries, United States Fish and Wildlife Service, Massachusetts Bays Program.
Status: Feasability study completed. Awaiting grant funding for the final design for the dam removal.
Schedule/Funding: Feasibility study completed Winter 2007. Currently working on Final Design and Permitting

Eel River Headwaters Restoration Project
Scope: The Town of Plymouth Department of Public Works Environmental Management Division is working with project partners in the restoration of approximately 40 acres of wetlands and 1.25 miles of the Eel River channel originating at the headwaters. The channelized stream will be restored to a natural sinous channel with riparian wetlands through the removal of the water control structures, re-grading of the bogs and the planting of new wetland resource areas, including Atlantic white cedar (click here for pictures). The final design plans are expected in the winter of 2007 for the wetland and river channel
restoration for bogs 1-7. The final design for the potential removal of the Sawmill Pond Dam located downstream is awaiting funding.
This project will provide potential new habitat for brook trout and significant reductions in nutrient loading downstream in the Eel River as well as restoring natural wetland functions and values on a large scale.
Hayden Pond Land Acquisition
As an expanded project scope, the Town reviewed potential land along the Eel River to preserve as conservation land. The Town has acquired a 13 acre parcel along Hayden Pond with $38,500 of the USFWS National Coastal Wetlands Conservation Grant (listed below) and $91,500 of Challenge Grant Money.

Pond Monitoring Program
Approved at Spring Town Meeting 2008
The Pond Monitoring Program was created to develop a baseline and assess water quality on a number of ponds in Plymouth. To date, four pond associations and 10 ponds are currently monitored. There are two portions of the monitoring program. The first includes the Biological Monitoring which is conducted by a professional biologist/limnologist. The second includes the Nutrient Monitoring which is conducted by each of the Associations.
Biological Monitoring - Water column profiles, secchi transparency, photoplankton sampling, macrophyte scouting, bathymetric data
Halfway Pond, Round Pond, Gallows Pond, Bloody Pond, Little Long Pond, Long Pond, Billington Sea, Little Pond, Great Herring Pond, Great South Pond
Nutrient Monitoring & Sampling - Collect water quality data, generate solutions & implementation strategies to improve water quality
Six Ponds Association Monitors: Halfway Pond, Round Pond, Gallows Pond, Bloody Pond, Little Long Pond, Long Pond,
Harbor Dredging
Scope: The Town of Plymouth Department of Public Works Environmental Management Division is working assessment, engineering and permitting to dredge portions of Plymouth Harbor. The harbor has not been dredged in decades resulting in safety concerns and loss of mooring areas.
