While there are some bad examples, there are lots of places where humans have played with the river and things have actually worked out pretty well. Especially considering that river hydraulics with flows varying over an order of magnitude presents a pretty chaotic system that's very difficult to predict or model.
I think it bears mention that the original "rapid" there was a decrepit diversion dam that had been thrown together with junk concrete over the years with no thought of downstream river passage. I'm not sure when but it later had a poorly designed boat chute added that sent boats right into a big rock at the bottom.
While I'm opposed to changing natural rapids, this was a case of a river-wide heap of junk that needed to be torn out and completely rebuilt. Considering where this probably was on the list of priorities for our cash-strapped state, I think it's great that they were able to come in last fall and rework it. Hopefully AHRA, CWCB, and the other funding entities will get it right this time.
