Pool 8 Islands, Phase III Habitat Rehabilitation and Enhancement Project   

St. Paul District

Pool 8, Upper Mississippi River, Miles 683 - 688, Vernon County, Wisconsin and Houston County, Minnesota, Congressional District: Wisconsin - 3, Minnesota - 1




Many of the islands in Pool 8 have eroded or disappeared, which has increased inflows to backwaters and wind fetch resulting in higher turbidity in the backwater areas and loss of valuable aquatic plant beds that migrating canvasback ducks use for food.
