Wanapum Dam
According to the guy on TV ... Crack is below the "fourth spillway gate".
Gates are numbered west to east. When I took this photo earlier in month ... there was more water leaking by the fourth gate from the west than any other. I know nothing about dam gate alignment ... water shown passing gate in photo may be completely normal. Rooting for a safe and speedy repair.
