MANKATO, Minn. (KEYC) - Exactly two years ago, crowds gathered in awe to watch the failure of the Rapidan Dam. Historic amounts of water caused flooding around the region, and the Blue Earth River was at all-time highs. That high water hit the dam, which became clogged with debris. Mother Nature carved her own path around the dam into the hillside, toward the house owned by the Hruska family and the Dam Store, and the rest is history.
