An ongoing dredging project in Lake Decatur is causing navigation hazards for boaters. Now in its third summer, the project’s floating rig and equipment sits between US-36 and E. William Street. That’s causing boaters to change course, and zig-zag from one side of the shore to the other. The multi-phase project is set to be completed by December 2019. Dredging crews have been-and will continue to work- in six phases that make up Lake Decatur. When the project is done, its capacity will be increased by nearly 30 percent. The Herald & Review reports that already, in some areas of the lake, the water is already as much as six feet deeper.
