The St. Louis District is responsible for maintaining the waterways that flow through a large part of eastern Missouri and southwestern Illinois. Located within the District's boundaries are 300 miles of the Mississippi River, including its four most southerly Locks and Dams and its confluence with the Missouri and Illinois River. Also included are several tributary rivers, dozens of other small streams, and five multi-purpose reservoirs - Lake Shelbyville, Carlyle Lake, Rend Lake, Mark Twain Lake, and Lake Wappapello.
The M.W. Boudreaux Memorial Visitor Center is located on Rt. J just south of the Clarence Cannon Dam. If you'd like more information, please feel free to email email@example.com or call the Mark Twain Lake Project Office at 573-735-4097.
