Pool 8 Islands, Phase I Habitat Rehabilitation and Enhancement Project
St. Paul District
Pool 8, Upper Mississippi River, Miles 685 - 688, Vernon County, Wisconsin,
Congressional District: Wisconsin - 3
Many of the islands in pool 8 have eroded or disappeared. This has increased wind fetch and associated turbidity in the backwater areas, resulting in a loss of valuable aquatic plant beds that migrating canvasback ducks use for food. The goal of the Pool 8 Island Construction-Phase I project is to preserve and enhance aquatic plant beds for fish and wildlife habitat.
