Yes, I live close by and have had some luck there but it's flour gold and not very much of it. If you want lead the creek bed and hill sides are full of bullets and fragments due to all the shooting ranges and target practice that used to go on up it the cyn. I have a few ounces of lead nuggets from there, the fragments get beat up and flat in the creek just like gold does. There's is a lot of iron trash too from when the Dam busted so MDing is a pain and almost impossible in some areas. Also you should know that all the watershed up here, San Fran., Bouquet, Santa Clara river bed is protected due to the Eco-terrorists and the Stickleback fish and can't be disturbed so no panning, sluicing, digging, or swimming in the creek. They even stopped stocking trout in Bouquet, now it's just a stream for the Sticklefish and we taxpayers can just look and take pictures of the creek. We used to ride our motorcycles in the Santa Clara riverbed but now thanks to the tree huggers we can't even pick up a rock in the creek. What we do is collect material in the benches and process at home. It's a pain but at least we're having some fun. You can get material from the creek too but you have to be fast and stealth like.
Be safe out there.
