1866
Congress authorized the Corps to establish a 4 ½ foot channel, to be obtained by dredging, building wing dams and closing secondary channels. Wing dams direct the river's current into a narrower channel, thus causing it to cut a deeper channel.
1907
Congress authorized a 6 foot channel project on the Mississippi, which wasn't complete when it was abandoned in the late 1920s
1930
The Rivers and Harbors Act of 1930 authorized the 9-foot channel project, which called for a navigation channel 9 feet deep and 400 feet wide to accommodate multiple-barge tows. This was achieved by a series of locks and dams, and by dredging. Twenty-three new locks and dams were built on the upper Mississippi in the 1930s in addition to the three already in existence.

Nature trails provide the public with a chance for a closer look at the natural landscape of bottomland prairie and wetlands within a sub-urban environment.

Educational Resources

The resource library is located at the Rivers Project Office in West Alton, Missouri. Educators can take advantage of the many publications on wetlands, habitats, and nature guides, along with engineering and navigation publications. Take time to surf the Internet to further research you project or interest. The herbarium is a also a great way to get a close look at native prairie grasses and forbs found in the Riverlands Environmental Demonstration Area.

Most of the written materials in the library were donated to the Rivers Project, by John Madson's wife, Dycie. John Madson was author of many books and articles. He had work published in the Smithsonian, Audubon, & National Geographic magazines.

Videos are an excellent way for people to learn about Locks & Dams, Eagles, Flooding, and Wetlands without leaving the classroom.
