On August 17, 1962, President John F. Kennedy stood behind a podium just north of Pierre, South Dakota. The President of the United States was here for the dedication of Oahe Dam, an earthen monster that created the fourth largest man-made reservoir in the world. 

Seven mighty Oahe turbines create enough electricity to power whole regions of the country. Oahe Dam stands 245 feet above the river bottom and required 92 million cubic yards of fill dirt, plus well over a million cubic yards of concrete.
