There are so many places lost beneath the waves around the world, you could create an alternate atlas of watery wreckages. But during the 20th century, the number of towns underwater increased exponentially as hydroelectricity projects submerged some to create power for many. These drowned towns were intentionally flooded behind new dams, their buildings removed or dismantled, and their residents displaced.
In recent years, droughts have allowed some of these towns to re-emerge. Others remain underwater. Here are 10 haunting waterworlds.
4. St. Thomas, Nevada
Located 50 miles northeast of Las Vegas, St. Thomas was established in 1865 as a Mormon outpost before becoming an agricultural community briefly known for producing cantaloupes and asparagus. In the 1930s, after the creation of the Hoover Dam, Lake Mead flooded, washing over the entire town. Today, during times of drought, the foundations of St. Thomas reappear — although each time they re-emerge, more of the structures have disappeared. In 2005, parts of 40 buildings were visible, including remnants of an old school and ice cream parlor. According to the National Park Service, much of the town is visible right now due to the current drought.
