What is happening about the sedimentation in Lewis and Clark Lake?
Update on the Sediment Management Plan, by Paul Lepisto, FOMNRR board member.
The Corps of Engineers shared information on potential methods to reduce sediment in Lewis and Clark Lake with the Missouri Sedimentation Action Coalition. The reservoir has lost over 30% of its storage capacity. The Corps and MSAC are developing a sediment management plan for the reservoir. It’s the Corps’ first sediment plan and it will be a template for Corps projects across the nation.
Methods, including flushing and dredging, will continue to be evaluated. Sediment impacts recreation, water intakes, hydropower and all uses of Lewis and Clark Lake. More information will be available in late September and the final report on Phase 2 of the sediment management plan is expected by the end of November.
