Before the large spillway project begins, the Corps will dredge and place riprap at the spillway to improve water flow efficiency. The $23.8 million contract for this project was awarded and is expected to complete by April 2028. Dredging removes sediments and debris from the spillway base, and riprap placement prevents erosion on the east bank of the spillway.
