What changed on the Penobscot River after the dams were removed?

The restoration of the Penobscot River is an unprecedented and innovative effort to remove two dams and build a state-of-the-art fish bypass around a third. As a result, thousands of miles of habitat along the Penobscot and its tributaries has been re-opened for 12 native species of sea-run fish.

How long does dam removal take?

2 ½ to 3 years
The dam removal process will take 2 ½ to 3 years because 15 million cubic yards sediment have collected behind the dams; the release of this sediment must be carefully controlled to protect a downstream fish hatchery, the Lower Elwha reservation, and the Port Angeles drinking water supply.

And below the dam, the natural flow patterns that native plants and animals are accustomed to are returned to their original configuration.
