Re: Hola from California
When I lived in Modesto, I would fish at Knight's Ferry after work for resident Rainbow Trout. A caddis hatch would happen like clockwork. The park rangers had to kick me out because they were ready to lock the gates.
There are some Steelhead runs in the Stan. I think that the big run (what's left of it) happens when the river is closed to fishing in November and December. Bob Nakagawa at Sierra Anglers in Modesto is a good source. He could probably give you more detail.
