190.4 Intake Towers

Several hundred feet downstream of the Highway 66 “Chain of Rocks” Bridge two beautiful stone towers rise out of the middle of the river that appear to be small medieval castles at first glance. Both are intake towers for the nearby Water Treatment Plant City of St. Louis (190.3 RBD) and serve as important landmarks for paddlers attempting to run the Chain of Rocks. You will want to stay a little to the right of these when the river is above 16SLG. Below 16SLG you will need to go left bank and make landing to initiate a portage. Above 20SLG your best route is to “make a touchdown” in between the two towers and go over the Chain directly below.

10.2 - 7.7 LBD Boston Chute You can enjoy a three mile passage through the bottomland forests lining Boston Chute, but be wary of a cross channel dike at bottom end which causes 3 foot whitewater waves in medium water levels.

Mile 13.0 - LBD Cache River Diversion Canal

13 LBD Cache River Diversion Canal The Cache River used to enter the Ohio River in between Mounds City and Urbandale, both upstream of Cairo, but now it enters the Mississippi 13 miles above Cairo, and about 20 miles from its old mouth. Go figure. Such is the nature of
