OLD TOWN, Maine (NEWS CENTER) --- A long-standing dam on the Penobscot River will start to be taken down on Monday.
The Penobscot River Restoration Trust will begin demolition of the "Great Works" dam in Old Town. Environmentalists expect the demolition to do great things for fish that migrate inland from the ocean such as salmon.
Dams like the Great Works block them from swimming upstream to spawn. The restoration trust is made up the Penobscot Indian Nation and several other groups. It bought the dam and two others on the river in 2010.
Members expect to have the "Great Works" dam out by September. They say that could improve migration for 11 kinds of fish.
"Also the alewives and the chad and the blueback herring are three species that we hope to restore to improve the ecological integrity of this watershed," said John Banks who is the Natural Resources director for the Penobscot Indian Nation.
The trust is looking to remove the Veazie dam next year -- and build a new fishway around the Howland dam by 2014.
