Site details

A state-park lake in the rolling hills of southern Arizona near Nogales, averaging about 80 feet deep near the dam, which is reachable only by boat or a long shoreline carry. It is a dark-water dive: light fades by 20 feet and divers report effectively zero visibility at 25 feet even with lights, so most stay at 10-15 feet along the rock wall near the day-use area to see fish. Paved walkways at the day-use area provide decent entries.
