Drifter's comments on logging are why Bob's book is some important to read. He walked the streams, he fished the streams, he snorkeled the streams, he electrofished them, and so on. He watched as floodwaters tore apart whole watersheds after logging. How pools disappeared, how channels shifted, how they became silted in.

If you don't have long-term data, whether it be fish counts, catch, flow, photos, and so on you simply don't see the changes.

I drove the same route to work for 30 years and the roadside trees dis not grow an inch. Amazing!.
