We spent the night at Sims campground on National Forrest land along the upper Sacramento River.  It was nice and cool with just a couple of other campers who were there for the fishing.  The river is very wide but only 2 to 3 feet deep in most places.  The fishermen were doing the fly fishing thing for trout.  The place is named for an old sawmill built well over a hundred years ago.  Back in the 1930's it was a CCC camp.  They built the Sims Bridge over the Sacramento River to access the eastern side of the river to fight forrest fires.
