U. S. Army Corps of Engineers plans to study existing Sediment Flushing Project to reduce uncertainty in the Lewis and Clark Lake Sediment Study

The Omaha District is evaluating sediment flushing at Gavins Point Dam in Phase II of its Lewis and Clark Lake Sediment Management Study as part of the Missouri River Recovery Program. Phase II of the study began in late 2012 and the initial numerical modeling analysis of 10 different management scenarios ranging from annual flushing to major dam modifications and dredging is complete. To help ensure the modeling results are as accurate as possible, USACE is expanding the study and building a numerical model of the annual reservoir flush that occurs on the Niobrara River at Spencer Dam, near Spencer, Neb.

Vegetation control to begin on Missouri River sandbars between Garrison Dam and Lake Oahe headwaters, N.D.

During September, the Omaha District will conduct vegetation management activities on sandbars in the Missouri River. Contractors will use a helicopter to spray sandbars with aquatic-approved herbicides to keep them clear of vegetation.
