Another unknown on how to deal with this is our ability to model and simulate climate patters in the season-to-subseasonal scale....

If you can say with confidence the region will experience significantly higher than average snow/rainfall over the coming months, then you could tailor your decisions to move as much water out as possible leading up to the rise in lake levels if you have high confidence.

Same goes on the flip side. If you have high confidence of a major dry spell, you can hold water back as much as possible.

Not saying it's a solution, but another tool that should be explored for dealing with this.
