Catfish, bullheads, caro, koi carp, bass, crawdads, squawfish, suckers, steelhead (a few left) bluegill, and turtles...turtles galore...

I am not sure of the species. I do sometimes see people fishing at Lake Almaden. Please Do Not eat anything from that lake! It is a toxic stew of Mercury and other things. The fish from lake Almaden are poisonous!
