What have been the impacts of regulation on Lake St. Lawrence compared to pre-project conditions?
• Lake St. Lawrence did not exist prior to the construction of the project. It was created by the construction of the Moses-Saunders hydropower dam, the Long Sault Dam and associated protection dykes. Prior to the seaway and power project, this part of the river was much narrower and contained fast-moving water and rapids. The area was also subject to ice jams and associated flooding. The seaway and power project has allowed for the growth of recreational boating and associated businesses in this area.
