Bonne Terre Mine Boat & Dive Tour Center

BonneTerreMine

In 1961, St. Joseph Lead Co. turned off the pumps that kept their mine dry. They sold the buildings to the state of MO which turned the area into a state park. Underground, clear, fresh water springs began seeping into the old mine. Little by little, a BILLION GALLON UNDERWATER LAKE was formed! There are 17 miles of underground shoreline, larger than the city of Bonne Terre which is above. 500,000 watts of lighting illuminate the caves both above and below the water. In fact, the water is so clear you can see 100 feet down! The air temperature is 62 degrees year round. The water temperature is 58 degrees year round. You can take a boat tour or a dive tour to see wonderful cave formations, ore carts, a steam locomotive, staircases, and other tools that were left behind when the last miner walked away. This underwater lake has become a world class fresh water dive site, named by National Geographic as one of America's top 10 Greatest Adventure (March/April 2000) In fact, it is the world’s largest freshwater dive resort. I'm not a diver, but I looked up some info for those who are:
