On the upper end, there are trees and stumps just off each side of the channel...MAIN LAKE. way out from the banks. Be careful there. It's about 2-1/2 miles up past the bridge.
On the lower end, stay east of the island. It looks ok between the West Bank and the island. But it is very shallow. Just go around it.
Those are the only spots I know that are hard on a boat.
Eat. Sleep. Fish.
