This lake is actually an obstructed stream, once dammed up to provide water to nearby Belmont. Now it's a fantastic recreation site, with several loops of trails that are good for hiking, running and biking.

Watch out for poison oak when hiking around Water Dog Lake! As long as you avoid the three-leaved menace, you'll find some nice dirt trails, and welcome shade from oak trees, around this lake.
