Plus you need to add in rising the power plant lower level and its equipment. That is your relief valve and needs to be restored and repaired first in my opinion. When working, it can release about 20,000 cfs, a third of what we are releasing now. When the main spillway is unusable as under repair, the only relief valve you have, as I understand it, is what comes out of that area of the dam. That needs to start in ten days as this last river of rain passes.
darn spell check changing words “add in repairing the power plant” — strike “rising.”
