My experience is with the lower Deschutes up to Shears Bridge from the early 70's on.
Oregon has been in major drought mode with the Cascade Mountains showing more bare rock in the summer time than I ever seen in 40+ years. Of course this effects water temps and water levels.
Here's proof of the temperature impact: http://www.oregonlive.com/environment/in..._colu.html
Now add to that a surface mount Lake Billy Chinook Hot water tap and you will effect the summer time vegetation that grows in the river. This will also effect what aquatic or semi-aquatic insect species can inhabit the river.
To draw water from the BOTTOM of Lake Billy Chinook instead of the top can only have a positive impact on the Salmon and steelhead summer time runs.
For you to include the John Day river in your comment (at least to me) shows me you don't know that river well at all - it originates in east central Oregon (the Blues) and has no dams other than irrigation diversions and has been a trophy small mouth fishery and small salmon & steelhead run as long as I can remember - nothing to do with the Deshcutes.
