High Water Cove is a protected freshwater site located within the Cerrito Recreation Area. As a zone closed to motorized vessels, it offers a calm environment suitable for beginners. Snorkellers enter from the shore, where a gentle slope leads into the water. Due to the high elevation of 6,400 feet and the water source originating from the bottom of the lake, the site remains cold year-round. Temperatures fluctuate significantly by season, ranging from the mid-30s °F in winter to the mid-70s °F during summer months. Facilities at the site include parking, toilets, and showers. The primary hazard for visitors is the cold water temperature.
