As the article says, it diverts most of the flow during low-flow periods (i.e. summer) which means there would not be much left for fish passage. Might be fine, might not, I don't know enough about the ecosystem to say. Additionally, there are some definite issues with sedimentation during construction. They excavated the channel to the intake and put all the dirt from the excavation into the stream for it to "carry away"[1]. This would not be allowed in most areas I know of - essentially, fish can't breathe if there's too much dirt in the water. Then several times it overflowed and eroded the channel - more sedimentation. The author even admitted using concrete liner would be the better choice, but opted not to because it was expensive - essentially, this externalized the cost of sedimentation to the ecosystem.
