Salmon Return: Dam Removal Offers Hope for Sandy River

Decades of dedicated work to restore Atlantic salmon to Maine's Sandy River watershed are gaining momentum with a significant dam removal project. For over a century, dams on the Kennebec River have blocked salmon migration, preventing their return to ancestral spawning grounds. Marine scientist Christman has spent 20 years employing innovative egg-planting techniques, slowly coaxing a few adult salmon back from the ocean to spawn.

Now, a $300 million initiative by The Nature Conservancy aims to remove or modify four dams downstream on the Kennebec River. This ambitious project, anticipated to take a decade, seeks to restore free-flowing conditions. The goal is to allow salmon, and other native sea-run fish, to travel unimpeded from the Gulf of Maine to the Sandy River. This endeavor faces opposition from some businesses reliant on the dams, but federal approval is pending.

The Sandy River watershed, with its cool, clean water and forested habitat, is considered crucial for salmon survival, especially in the face of climate change. While marine survival rates for Atlantic salmon have declined globally, the restoration of this critical habitat offers a glimmer of hope for re-establishing self-sustaining runs in Maine.
