I'm sure it wouldn't be great for natural reproduction as there is very little in the way of stone or gravel in the creek, but there is some good deep holes. They designed the creek with spawning migratory fish in mind from what I have heard.
I was hopeful that a few may find there way up there each spring, somehow the Chinooks make it up there in the fall and I am fairly sure that they didn't originate (hatch) from the Creek.
