The Sabattus River cascades over a dam Tuesday morning behind the Farwell Mill off Route 196 in Lisbon. The Upper Town Dam that was just beyond the Webster Road Bridge, middle right, was removed last year. Conservationists are aiming to remove or construct fish ladders over the five remaining dams on the river in the next several years, opening access to 75 miles of river and stream habitat for migrating fish, especially alewives. According to Casey Clark, marine scientist at the Maine Department of Marine Resources, “Design plans for partial removal of the Farwell Dam and construction of a nature-like fishway will be complete in October of this year. Once plans are complete, we intend to share them with town leadership and have a meeting in Lisbon for the public to review the plans and provide comments. The department has secured about half of the funding needed and is actively working to secure the remaining funding to complete the project. We aim to complete the project in 2024 to meet our funding requirements,” Clark said. Russ Dillingham/Sun Journal
