Dive-site story
Set in the Black Hills of South Dakota, Pactola Reservoir is a high-elevation freshwater destination formed by the damming of Rapid Creek. Divers explore submerged foundations remaining from the flooded historic mining settlement, along with sunken boat wrecks and fish shelters installed across the rocky lakebed. Pronounced thermoclines develop during the warmer months, making thermal protection essential as you descend through the water column.
