Prosser Creek Dam Basin Cleanup
Remove all materials from the spillway stilling basin. These materials include, but are not limited to fine sediments, gravels, cobbles, boulders, chain link fence materials, and large woody materials. Remove material that is present in the 6-inch drains on two of the chute blocks to the greatest extent possible. Perform an inspection of the concrete floor and all other spillway stilling basin features upon completion of the sediment and materials removal.
