How high is it running right now?
There are two awesome hikes out of the river starting with virgin spring which has petroglyphs and a perennial spring at its alcove.....under a mile from the river. Also down river a bit is a confluence with Cane wash which goes a ways up from the river....has a narrow and tall canyons. There is a trail that runs the entire course of the river...it gets ambiguous in some parts but it would be tough to get lost.
As far as camping is concerned there seemed to be some good camping all the way through the river....
