Communities and School Districts within the Anchor Bay Watershed
Local communities within the Anchor Bay Watershed are working to protect the Anchor Bay, Lake St Clair, and the tributaries and drains leading to the Anchor Bay. These communities have developed the Anchor Bay Watershed Plan, which is a blueprint for improving and protecting the Anchor Bay. The plan was first completed in December 2003, and was updated in 2006.
