Site details

A Salt River reservoir in the Tonto National Forest northeast of Mesa, dived mainly at the Keyhole cove (with a dock allowing a giant-stride entry) and Vista Point. It is a low-visibility desert lake — typically up to 15 feet at best, with a sharp thermocline around 19 feet in summer dropping temperatures 6-10 degrees — used by Phoenix-area divers for convenient training and night dives. Silty bottoms demand careful fin technique.
