Volume released at failure (ac-ft)
Additional Remarks or UpdatesJanuary flooding eroded rip rap between the stilling basin and tailwater weir; April/May flooding exacerbated the situation. May 16 a section of the East wing wall was observed to be displaced; rip rap was placed to stabilize the wall until the waters receded to get a better understanding of the situation. In June, once gates were able to be closed; a diver noted up to 6-ft of undermining along the stilling basin endsill, 200-ft of the tailwater weir was gone; and a large scour hole between the endsill and tailwater weir was observed. Emergency repairs included placing concrete along the damaged areas; CFD analysis was performed to determine best options for gate operations going forward (especially if gates are out of commission); final permanent repairs are in design phase
