Site details

Lake Murray, inside Oklahoma's oldest and largest state park near Ardmore, is largely spring-fed and offers rare clarity for the southern Great Plains - up to 30 ft on good days, though commonly 5-15 ft. Marietta Landing campground on the south end is the primary dive access, with bluffs, cracks and overhangs to explore in the 25-60 ft range; the lake gets dark below about 40 ft. The WPA-era Tucker Tower area across from the marina is a deeper boat-dive option.
