Does anyone have any idea if there will be bad flooding downstream just from what is currently happening? The normal spillway is one thing. But the emergency spillway is at least doubling what the normal spillway is releasing.
From my easy chair on the other side of the continent...
They’ve been sending the maximum flow through the main spillway for a few hours and the flow through the emergency spillway has been reduced to near nothing.
So they should be able to run the main spillway at the max for 4 or 5 more hours and have the lake level down enough so they can fill in the main spillway with rock and concrete before the level got to the top again.
Then they can let water out the main spillway fast enough to keep the level safe- below the emergency spillway- henceforward.
So, it looks good.
