The amount of sediment flowing into Lewis and Clark Lake from the Niobrara River have groups struggling to find a solution. Too much sediment increases the lake levels and flooding. At a meeting of the Missouri Sedimentation Action Coalition Tuesday night in Niobrara, a presentation by the US Geological Survey showed how flushing the Spencer Dam has moved sedimentation down the Niobrara.
It was hoped this study could help determine if the flushing method would be feasible for Gavins Point Dam on the Missouri. MSAC Board Member Butch Becker, and several others in attendance, believed that the study held little relevance to Gavins Point and Lewis and Clark, because the lake is much bigger than the small pond above Spencer Dam…
Becker has spoken with different groups and the Corps of Engineers to try and develop a way to move the accumulating sediment out of Lewis and Clark Lake and down the Missouri River…
Studies have shown that more than half of the sediment delivered into the lake comes from the Niobrara River. Becker says that is where they have to focus…
MSAC is a coalition of landowners, energy company representatives, related agency members, and any interested residents who work to reduce sediment, animal waste, and nutrients that drain into the Lewis and Clark Lake.
