Rock Island
Rock Island is a Table Rock Lake island dive.
Boat-access freshwater island dive on Table Rock Lake with mooring-and-shore entry, cold deep water, and good summer visibility.
About Rock Island
Rock Island is a boat-access freshwater island dive on Table Rock Lake with shallow rim water, a deeper northeast drop, and easy shore-entry logistics from a moored boat. Summer clarity and colder water below the thermocline shape the dive, and the lake's bass-and-catfish habitat keeps it interesting. On busy weekends, the surface plan matters as much as the bottom time.
