 The St. Joseph County, Michigan Sheriff's Office is asking Michigan boaters to limit their wakes as much as possible until the high water recedes. Lake levels are dangerously high, and heavy wakes can cause damage to the ecosystem, the shoreline, and the docks, according to officials. WSBT reports that trees and boat docks are more underwater than usual, and officials are trying to avoid bigger impacts in the future by asking boaters to slow it down along the shorelines.
