Putah Creek Council is sponsoring a Creek Speak with Peter Moyle. He is going to talk about native fish in Lower Putah Creek. I would guess it will be mostly about how PCC is trying to get salmon back into the creek!

I spoke with him at the Cal Trout Dinner last week and he talked a lot about that proposal. Sounds intriguing.
