The spring boating flows for Black Canyon are starting.
The normal flow is about 70 to 100 cfs. The boater flows are up to 900 cfs. This is class 5 white water.
These high flows also are frequently mirrored in the flows below Oneida Dam. Take care in either area

Pacificore water release info is available on their website for below Grace and Oneida Dams.
I know that they pit tagged a bunch of cutts to see how the flows affect adult fish. I don’t know the results of that study. I also am curious on how they affect young fish.
Best information would be if you called the SE Idaho F&G office and talk to Dave Teuscher.
The kayak groups lobbied to get these whitewater flows. At least they flush some of the sediment downstream.
I believe it has made the fishing much better by doing the larger flows the river bottom is much cleaner with a lot less mud
It should, its essentially putting the river to flood stage like what would occur with spring run off each year. This is always a good thing for trout as it tends to clean out gravel bars and spawning areas.
