I am going to the Cowlitz R. to float from Mayfield Dam to the Trout Hatchery. I have put it off for a while due to the reputation the river has for it's combat fishing. If anyone has river information: hazards, routes, fishing tips, etc., I would appreciate them very much. Also, is the fishing/float better at the current river levels (4000 cfs) or at higher flows? Thanks!
