Editor’s Note: Thanks to the Department of Public Works for this update on Fawn Lake dredging. Please note the July 31 updates to the Trail Map
As part of the Fawn Lake restoration project, work to reconstruct the outlet dam at Springs Road is scheduled to begin August 3. Dredgit’s subcontractor, Bay State Regional Contractors, will have equipment staged at the dam to remove the existing debris and regrade the area for the new earthen dam. In order to perform this work, a cofferdam will be set across the end of the lake and water will be pumped around the temporary dam. Steel sheeting will be driven along the length of the dam to act as the new support. Specifics for this work are shown on pages C-4 & C-5 of the contract documents found on the Fawn Lake website (see link below). Due to the amount of construction equipment, the existing trail through the work zone will be closed. Please use one of the alternate trails as shown on the attached map.
The dredging work in the lake will also begin next week. The lake is not being drained.
The weed harvester will first cut the aquatic vegetation below the surface of the water and haul it to shore up the boat ramp. Once that material is cleared, the dredge barge will cross back and forth, making 6-foot wide cuts in the sediments which will be pumped to shore, screened, dewatered, and trucked off-site. Trucking of the dried material will be daily, starting at 8 am.
Due to social distancing, please do not approach the contractors with questions. We urge you to check the project information, previous reports, construction plans and proposed work schedule on our website at https://www.bedfordma.gov/department-of-public-works/pages/fawn-lake-project
