Hughes County, South Dakota

Pierre - South Dakota's state capital and one of America's most remote capitals - from Pierre's geographic isolation (with a population of about 14,000, Pierre is the second least populous state capital in the United States - its position in the exact center of South Dakota, 220 miles from the nearest large city, and its isolation on the Missouri River make it one of the most remote state capitals in America) to Lake Oahe (the massive Missouri River reservoir - the fourth largest reservoir in the United States, stretching 231 miles from Pierre to Bismarck, North Dakota - provides exceptional walleye and salmon fishing that draws anglers from across the region) and the Oahe Dam's significance.
