Upper Mississippi River – Navigation and Ecosystem Sustainability Program: Johnson Island Project, Wisconsin

The Navigation and Ecosystem Sustainability Program is a long-term program of ecosystem restoration and navigation improvements for the Upper Mississippi River System. Johnson Island is located near Trempealeau, Wisconsin, in Pool 6 of the Mississippi River. Island erosion, island dissection, and sedimentation have greatly reduced the quality and quantity of terrestrial and aquatic habitat in the project area. Project objectives are directed at improving conditions for fish, aquatic and terrestrial wildlife, maintaining emergent vegetation, maintaining submersed vegetation and island stabilization and nourishment to restore connectivity, and promotion of floodplain forest regeneration.
