Back to the drawing board on Hebgen Lake repair (Must read)

I notice a lot of people have been reading this story on the gate failures at Hebgen Dam, the news of which was first brought to us on Sept. 1 by “Idahosal.” (Salle)

They thought they had the way to fix the broken headgates at the dam, but it failed.

The news now is grim. The bulkhead plan did not work. There was too much turbulence at the dam intake for them to place the steel plate and stem the flow. At the moment there does not seem to be a “plan B”. The flow is still at springtime level. They are losing more than 5 inches of reservoir water elevation every 24 hours and this will accelerate as the level drops due to the cone shape nature of the reservoir bed. There are two scenarios that are scaring us at the moment.

Hebgen Lake Dam malfunctioning. Evacuation?

I’ve just learned from Salle E. that something is wrong with Hebgen Dam near West Yellowstone and the area downstream is being evacuated due to flooding flows of the Madison River.

I see nothing on-line yet.

Update. Here is a news story. It looks like a gate is stuck open and a lot of water is flowing into the reservoir from heavy thunderstorms.

Update. Sunday. Sept. 7. Apparently this is still not fixed. Engineers are fashioning some steel “bulkheads” and so plug the headgates that became stuck open. Last week they were removing concrete from the water intake tower. After that the bulkhead will be lowered down. I believe the Madison River flows are still about 4 times normal for this time of year.
