We know the problem. Low Dissolved oxygen. Really only a problem when it gets hot.

Solutions:
1.inject O'2
2.Weir Dam
3.Devices on Turbines
4.Min Flow
5.Boulders in River

#1...Injecting oxygen is a technical solution that is expensive. However it will solve the problem in a hurry.

#2 A weir dam across the river would create a waterfall that would add DO and do it with out long term expense.

#3 I think this has been tried and have been removed.

#4 MMM...This would probably be harder to get that O2 injection.

#5 Putting boulders and other stuff in the river to create water breaks wouldn't work very well without min flow.


I figure #2 (Weir Dam) in conjunction with some O2 injection is feasable.

Falling water = O2.
