YANKTON, S.D. (WNAX) – Flooding in the past month should not have a big impact on efforts to create a sediment control plan for Lewis & Clark Lake.

Paul Boyd, a hydraulic engineer with the Corps of Engineers, spoke to the annual meeting of the Missouri Sedimentation Action Coalition in Niobrara this week.

Boyd says he continues to work with the coalition on defining the management plan.

Boyd says they are still working on Phase One.

Boyd says despite all the past studies, they don’t have an overall report on the costs and benefits of any sediment management plan.

The coalition is continuing to raise money from Nebraska, South Dakota and local governments to continue funding their ongoing studies.
