Coastal response to the Port Sheldon jetties at Pigeon Lake, Michigan. Final report
The Consumers Powers Corp. constructed two jetties at Port Shelton, Michigan to maintain an open waterway into Pigeon Lake. These jetties are located at the entrance of Pigeon Lake in Port Shelton township, on the eastern shore of Lake Michigan. Originally, water was drawn from Lake Michigan via Pigeon Lake Inlet to cool a fossil fuel power plant. The inlet into Pigeon Lake was deepened and widened throughout the early history of the power plant. Adjacent shorelines have been modified directly by Consumers Power Corp. and indirectly by the natural littoral response to the jetties. This study sought to determine the impact, if any, of these jetties at the entrance to Pigeon Lake on adjacent shorelines and nearshore zones. Analysis of historical shoreline position and bathymetry data in the vicinity of Port Sheldon indicates approximately 810,600 cu yd of material has been trapped by the jetties since construction in 1964. At present, it appears that the fillet areas adjacent to the jetties have volumetrically stabilized and that natural and bypassing may be occurring around the lakeward tips of the jetties. Results of this study identified a zone of slightly higher erosion 3,000 to 9,000 ft south of the jetties that may be related to jetty construction.
