Army Corps of Engineers officials have unveiled plans to improve wildlife habitat along seven miles of the Mississippi River near Herculaneum. The public is now getting a chance to review the plans. The Corps proposes building a number of U-shaped rock structures in the river, shortening some of the current stone dikes that jut out into the river and cutting notches in others.
The Corps says the changes would create small islands and side channels away from the navigation channel that will improve habitat for fish, birds and other wildlife.
