yes, they go all the way up to below the dam at trailbridge, that is the "natural" spawning beds where the "native" fish spawn. The upper river is loaded. No one previously wasted their time fishing above leaburg because there were no "hatchery" fish. I think the hatchery recycles fish downriver a couple of miles from the hatchery, but I'm not certain on that. All the fish with amputated fins, in theory, go up the creek back into the hatchery. I don't think they're going to be clipping fins on mckenzie fish anymore however, heard the ODFW guy mention it, as steelhead are not a native species for the river to begin with, all of them are of hatchery stock that have been spawning successfully on their own, and as a result, they have somewhat taken over the system, hence the change in the regs.
