Summerville / Berkeley County creeks
The historical 'megalodon capital of the world.' Summerville and the surrounding Cooper-Ashley-Edisto river drainages have produced more giant teeth than any other US locality. Most prime ground today is private; legal hunts run via licensed guides on the rivers themselves.
Event timeline
Cooper River Fall Low-Water Window (SC)
upcomingOctober through early December typically brings the lowest, clearest water on the Cooper, Stono, and Ashley rivers — peak season for licensed dive hunts on Chandler Bridge and Ashley Formation gravel.
Charter a guided dive or kayak hunt with a licensed Charleston-area outfit. Surface-collect gravel bars on the Cooper, Stono, and Ashley at extreme low water. SCDNR licensure is required.
South Carolina rivers below the high-water mark are state-owned and open with a Hobby Diver License (SCDNR). Private land along the rivers is strictly off-limits without permission.
SCDNR Hobby Diver License is mandatory for collecting from state water bottoms. Quarterly reporting of significant finds is required. Land sites need landowner permission.
