Site details

A huge, deep, clear reservoir on the Green River near Dutch John with some of Utah's best freshwater visibility (20-40 ft). Established dive areas near the dam include the Cart Creek Bridge wall dive, Mustang Ridge, the Visitor Center shoreline, and the islands (Osprey/Gilligans) with walls and pinnacles. The reservoir is over 400 feet deep in places, so divers pick their depth on the walls; below the thermocline it gets dark quickly.
