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

Partners

  • USFWS
  • WIDNR

Description

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.
