A dam owned by the Town of Penobscot on Winslow Stream, a tributary of the tidal Bagaduce River, was used to maintain the water level of Wight Pond. It was replaced with a fish passage in 2017 to allow alewife to access the pond for spawning while still maintaining the water level.[1]
The 20ft (6.1m) tall Coopers Mill Dam was removed from the Sheepscot River in 2018. One year later, the furthest downstream barrier on the river, the 15ft (4.6m) tall Head Tide Dam, was partially removed and replaced with an elevated platform to allow for fish passage. The Head Tide Dam was a former grist mill dam that was purchased by the Atlantic Salmon Federation and the Town of Alna for the purposes of removal.[4]
The 35ft (11m) Lower Montsweag Dam on Montsweag Brook, a tributary of the Sheepscot River, had been built to create an emergency water source for the Maine Yankee Nuclear Power Plant. The dam was removed in 2010 following the plant's decommissioning in 1997.
St. George River
At the time of its removal in 2002, Sennebec Dam was the last man-made barrier on the St. George River. The dam had raised the natural water level on Sennebec Pond, and was replaced with a fish ramp that maintained the level while opening 17 miles (27km) of the river and 1,100 acres (450ha) of lake habitat to fish passage.[5]
