A low earthen dam separates Crystal Lake from the larger Baum Lake, with a short wooden bridge across the outflow where the water drops a few feet. This is probably the last good place to access drinking water before continuing north along the PCT, with the next secure source of water on the trail after 10 miles at Burney Falls, though after about 4 miles there's a possibility to cut over to the Burney Mountain Guest Ranch, even if it might be closed for guests, water should be available in a pinch.
