Diversion Gate Trial Operation April 12

Current Opened Gates: Automatically #8 ~ 18

Central gates #8 ~18 were opened automatically (Figure 1). Gates were set 3.5 ft water depth and 2.8 ft was measured on PLC screen.

Erosion at the fish passage entry is still in progress (red circle in Figure 2). It may be caused by the recently formed sand bar (green circle in Figure 2).

River current hits the sand bar and reflects flow direction to the fish passage bank.

Sediment has been deposited and grown at the north deck as shown in Figure 3.
