A while ago, maybe still, the California record for sport caught coho came from what was then called Papermill Creek (now Lauganitas Creek). It ran right past my first home there. Not a big creek. Still has a few coho.

The premier study on coho and steelhead (Shapavolov and Taft) was on small stream that I also lived near for a while (Waddell Creek). Runs of 500 steelhead in a **ckin creek. Now, what do we get in rivers ?

It was interesting that even then, with "only" the ocean fishery, that the R/S for coho back to the creek was <1. In the 30s and 40s.........
