City manager, David Cole, said it benefits the city and environment.
The Branch Lake Stream Dam will soon be gone.
"This dam has, like I said, has been abandoned for some time," Brett Ciccotelli from the Downeast Salmon Federation said. "It used to be the old city water supply dam, so it's a liability because it's concrete and in the stream and decomposing."
About 2 years ago, members from the Downeast Salmon Federation approached Cole about removing the dam.
"We thought it was a good idea," Cole said. "At the staff level, we've been working with them. We said if you can raise the money, we can bring it to City Council."
On Monday, City Council members unanimously voted to approve a Memorandum of Agreement that would allow for the removal of the Branch Lake Stream Dam.
"It's an exciting opportunity to partner with the city, so it's great," Ciccotelli said.
The Downeast Salmon Federation exists to protect Atlantic Salmon.
Ciccotelli said there are few places in Maine they have a habitat.
"It would make the river safer for kayakers," he said. "Then for us, as a fisheries conservation group, we're really excited to open up all this habitat."
Cole said the Downeast Salmon Federation will be funding the dam's removal.
