Dikes on the left and right sides of the spillway channel will train the flow into the chute structure and provide flanking protection to prevent erosion from initiating outside of the spillway channel. The spillway modification also includes lowering of the upstream spillway channel and the approach channel to 6 to 8 feet below existing grade 

Together, the chute structure and stilling basin will prevent the initiation of spillway erosion at the downstream end of the spillway.  Dikes on the left and right sides of the spillway channel will train the flow into the chute structure and provide flanking protection to prevent erosion from initiating outside of the spillway channel.
