Evaluation of Water Level Reduction as a Habitat Management Tool for the Upper Mississippi River

The diversity of habitat types, plants, and animals in the Upper Mississippi River has declined considerably over the last 50 years, creating loss of aquatic vegetation, loss of islands and side channels behind dams, and changes in river sediments, potentially caused by the method of managing water levels, which maintains artificially high water More...
