On its face I totally agree with this. It is amazing how animals can adapt. Humans are really adaptable animals for example. Maybe the most adaptable animal? But it’s not like you can just dam, dike, drain, de-water, and straighten rivers and streams and expect the animals that adapted to the unaltered habitat over a long evolutionary process to quickly adapt to the new conditions. Look at Upper Columbia fish. They haven’t adapted to the altered Columbia too well. But that’s not what you meant, right? If not, what did you mean? Upton, my original statement about the “ditches” being streams was just coming from my background working with agricultural landowners. Once the lowland streams get out of the hills and hit the valley floors, they’ve been altered so drastically and for so long that folks often forget that that’s where the fish live! They don’t look much like how folks picture salmon streams—they look like ditches, and are often managed as such, and that doesn’t do the fish any favors. Thanks for saving juvenile fish that needed saving!
