I was advised by Fish and Game in the early 70s that dam number 808 (Lake Los Serranos) is so heavily polluted by run off that the fish would be toxic. Fish but use rubber gloves and goggles. Says Flem
Can you fish in lake serranos? Says DJ
Near Lake los Serranos you find the Fern Canyon Trail which is a tremendous hiking trail. Going for a horse ride at nearby King Performances Horses is always a fun thing to do. Going for a hike on the West
Fork Trail is always a great adventure; in case you yearn for fishing you can always pop by H & L Charter CO. Don't leave Lake los Serranos without stopping by Chino Hills State Park; petting zoo's are enjoyable for everyone, All God's Creatures is one of those and it's in close proximity to Lake los Serranos.
