CAMDEN — A workshop will be held Thursday, Oct. 14 in Harbor Park with Camden Select Board members and consultants, engineers and scientists who worked on the new Megunticook River Feasibility Report.

Board members and members of the public will have the opportunity to hear presentations from those who prepared or contributed to the report and to ask questions.

The event takes place from 1 to 3 p.m.

The full report is posted on camdenmaine.gov. It was released by the Select Board Aug. 24. At that time, Town Manager Audra Caler suggested the Select Board discuss the study at a future meeting.

The report covers the area from Camden Harbor to Lake Megunticook and promotes a greener, heathier river, fish passage up to the lake, and removal of the Montgomery, Knox Mill and Knowlton Street dams.  Dam removal is considered a measure to reduce flooding in downtown Camden and improve the environment of the local watershed and regional waters.

However, the report states “dam removal alone may not result in lowering the FEMA base flood elevations below the Camden Public Safety Building that is located directly adjacent to the Washington Street Bridge.”

Structures beneath the Brewster Building and Washington Street bridge itself also influence flooding in this area, according to the report.

A great deal of new information is available in the report, such as the measured amounts of sediment behind the downtown dams and chemical analysis of that sediment. Chemicals in the sediment behind all the dams are similar to what is found in Camden Harbor, according to the report.

The largest deposit of sediment is behind the Knowlton Street dam, which would drive up the cost of removing the dam into the $3 million to $5 million range, according to the report.

The report is divided into sections including: an executive summary, goals and objectives, history of seven dam sites, evaluation of current river conditions in areas impacted by the dams, sediment behind the dams, hydraulic analysis, climate change impacts on the river and flooding models, fish passage, options for the dam sites, environmental issues, cost analysis and restoration and resilience design considerations.

The written report is about 180 pages. Visual information includes over 100 photographs, maps, designs for dam options and fish passage, and charts and tables presenting scientific data and analysis.
