Unfortunately the national zeitgeist assumes fish barriers = bad. Here in the lower Colorado River Basin where most of our habitat is full of exotics, we are adding fish barriers and renovating streams to restore native fisheries. Fish barriers = GOOD here for the most part. It is important for everyone discussing barriers that the automatic "barrier=bad" narrative be qualified as to whether a particular barrier is a negative or positive impact on native fisheries!
