About Oahe Downstream

Oahe Downstream presents a refreshing cold spring experience right below the Oahe Dam in South Dakota. This primitive swimming hole offers a unique connection with the powerful tail waters, blending natural coolness with the dynamic flow of the river. Its raw, rugged environment invites you to immerse yourself in an authentic outdoor setting away from developed facilities.

Getting There

You can reach Oahe Downstream easily by car, with ample parking available close to the water’s edge. No hiking is necessary, making this spot accessible for those looking for a straightforward way to enjoy South Dakota swimming holes without long treks. The convenience of drive-up access sets it apart from more remote hot springs in the state.

What to Expect

The water here is cold and fast-moving because of the dam’s outflow, creating an invigorating but potentially challenging swimming experience. The surrounding atmosphere is peaceful and natural, though you must remain cautious of strong currents. Facilities are minimal—there are no developed amenities, preserving the area’s primitive nature.

Tips for Visitors

Visit during summer to fully enjoy the cooling effect of the cold spring waters. Bring sturdy water shoes and keep a close watch on water conditions due to the swift currents. There is no fee to swim, but exercising safety and respect for the environment is essential when exploring this distinctive spot among South Dakota’s swimming holes.
