The Seal Cove Pond Fishways Project
The effort to reconnect Tremont’s Seal Cove and Seal Cove Pond and improve fish passage is complete!
Seal Cove is one of a few public waterfront sites on the “Quietside” of Mount Desert Island. A town park provides access to the water and a picnic area. Visitors can enjoy the stillness of an early morning fog, the splendor of the setting sun, and take in the sights and sounds of the local fishing industry.
Historically, the connection between Seal Cove and nearby Seal Cove Pond was compromised by dams. Of greatest concern is the way these barriers (even the one with a fish ladder) prevented alewives from reaching Seal Cove Pond to spawn.
In 2017, we began working with the Town of Tremont, Acadia National Park, and other partners to improve fish passage at two key locations along Seal Cove Brook—one at the current dam at Seal Cove Pond and the second downstream at the site of a former dam. Construction of these fish was began in July of 2022 and was completed as of September 2022 (pictured at the top of the page).
Alewives are food for mammals, birds, and other fish. They are vital to the health of the pond and the ocean. They are also a valuable source of bait. Diminishing alewife populations directly impact commercial fisheries and local livelihoods.
This project was a collaboration between Maine Coast Heritage Trust, the Town of Tremont, and a host of supporting organizations—including Acadia National Park, as well as a handful supportive landowners.
If you love MDI and the coast of Maine, and care about the natural resources on which healthy environments and communities depend, please consider supporting this effort.
Your gift will:
- Construct nature-like fishways at two key sites on Seal Cove Brook
- Bring back 60,000 alewives to Seal Cove Pond each year
- Improve the health of the Seal Cove Pond watershed
- Contribute to the recovery of Gulf of Maine fisheries.
