How Removing One Maine Dam 20 Years Ago Changed Everything

The removal of the Edwards Dam on Maine’s Kennebec River helped river conservationists reimagine what’s possible.

SNIPPET:

As soon as the dam came down, the river rebounded. Fish immediately had access to 18 more miles of habitat, up to the town of Waterville at the mouth of the Sebasticook River. Atlantic sturgeon began to swim past the former dam site, and alewife and shad soon returned. Within a year seals could be seen chasing alewives, a type of river herring, 40 miles upstream from the ocean.

And with alewives coming back, so did everything that eats them — river otters, bears, mink, bald eagles, osprey and blue herons.

But the best indicator of the ecosystem’s recovery was the resurgence of aquatic insects like mayflies and stoneflies, which signaled improved water quality.
