Its monday night and the lake level is almost 8 feet below the emergency spillway, today they dropped riprap and pumped grout into a fissure gouged out by the water, a fissure nobody is talking about. Its stable for now, they cannot use the emergency again and are calling it the auxiliary instead. They cannot prep it enough to use again. Total design failure even at a 5% release rate.
36 hours is the current estimated time left, it’s literally dammed if they do, dammed if they don’t.
Main spillway is at 100,000 cubic feet per second, undamaged it can go more than twice that rate but will flood downstream.
Really depends on the next storm, final solution is they must drain lake low enough so that even with the spring melt they won’t need to use the main spillway which may take six months to rebuild if they went all out. But they also need to get the pennstock valves open at the powerhouse, its flooded.Must get wster below main spillway gates.
I envy the guys sitting across the dam doing live streaming.

All right, I just got home. Where are we at?
Clearly O town is f***ed. The latest pictures show the cracks right beneath the Espill are the deathblow. Anyone with half a brain knows that it’s not Fill it’s decomposed granite or who knows what that’s just rock sitting on top of a rock.
( The word from the people working on it who are not allowed to talk publicly is there are seven monster cracks beneath the emergency spillway )
