146.2 - 144.5 LBD Osborne Island

Extensive sandbars at low water surround Osborne Island, but no protection, and it will be a noisy camp due to all of the industry of Buzzi Unicem, a giant cement manufacturing operation downstream on the main channel. Both sides of the main channel are sometimes used for their fleeted barges. The main line dikes are notched along Osborne to assist fish migration to their natural spawning grounds. Fish like sturgeon, spoonbill catfish, and buffalo are sensitive when time to spawn having to travel long distances to reproduce. Best bet: dive into the back channel of Osborne Island (which opens up around 6SLG) and find a quieter campsite away from all of the hullabaloo. We found hree bald eagles feasting on gar on sliver island at the bottom of the back channel.

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
