Impact from dams on fisheries has been a concern since the 1700’s, by Impact from dams on fisheries has been a concern since the 1700’s, by 1950’s the condition of the river reached its all time low, treatment plants 1950’s the condition of the river reached its all time low, treatment plants reduced pollutant discharges following Clean Water Act but non-point reduced pollutant discharges following Clean Water Act but non-point sources of pollution increasedsources of pollution increased
Interest started in 1992 when Maine Department of Inland Fisheries Interest started in 1992 when Maine Department of Inland Fisheries successfully reestablished a trout and salmon fishery just below Sebago successfully reestablished a trout and salmon fishery just below Sebago Lake and after plans for the removal of Smelt Hill Dam and improvements Lake and after plans for the removal of Smelt Hill Dam and improvements in water quality from cessation of SAPPI Fine Paper’s pulp mill. in water quality from cessation of SAPPI Fine Paper’s pulp mill. Development pressure increased after removal of the pulp mill since the Development pressure increased after removal of the pulp mill since the stench and unattractiveness of living near a pulp mill was also removed. stench and unattractiveness of living near a pulp mill was also removed.
