I did some trips with USGS and the driftwood down there plays a significant role in habitat for fish and insects. You would be shocked at how low key and significant the science is that goes on down there. You may float past a drift wood
Pile and never notice it in an eddy, but if you took a close look, you may find an antenna or wire hanging in the water, and sticks tied together to create shade beneath the surface. It's pretty incredible, but due to the dam, no irregular or seasonal floods
And little pine wood from the high country. Therefore another example of side effects downstream including as I mentioned, insect habitat and fish eggs habitat. It all ties together, debris, sediment, viscosity, water temp. There's really no wood down there compared to what was Predambrian era and there's a lot of govt funds invested in protecting the few native fish left, as well as the bats.
