Not sure if this is true and I have no knowledge about such things, just passing on what I read.

This is Higbeans back yard maybe he has more and better info?


That doesn't seem to make sense. The water going into the turbines comes in far below the level of the spillway, and IIRC the intake is screened. If they've had to shut down the turbines, there must be something else to it.

It's been several decades since I toured the interior of the facility and can't remember - isn't there a bypass?


I read the same thing; elevated river levels compromising the discharge flow from the plant.


Well, this is starting to make some sense,....

A.) The backwash / reverse flow / elevated river level from the main spillway hydraulically stalling the turbines ( the discharges of which are not screened ?)......
.


Honest question here....

The intakes for the turbines are two giant "tubes" running down the slope on the south side of the reservoir. They're screened on top, and, IIRC, have gates to choose at which level the water is allowed in. They can therefore take water from a much higher pressure than the water backing up at the discharge. How can that stall the turbines?



Lunatic fringe....we all know you're out there.
