Before the Water Rose
Starting as a pioneer settlement in 1865, St. Thomas grew to be an established town of farms, homes and stores. Life passed slowly until Hoover Dam was built. St. Thomas was doomed as the rising waters of the Colorado River slowly filled canyons and valleys, creating Lake Mead. The residents of St. Thomas sold their land, tore down homes that had been lived in for generations and said goodbye to friends and neighbors. On June 11, 1938, Hugh Lord rowed away from his house, the last citizen to leave. The community was soon covered by the lake, a victim of a rapidly changing landscape and lifestyle in the desert.

While we cannot bring St. Thomas back to life, we can show the town and its people the respect we’d like our home town to receive. Please do not climb on foundations or disturb any artifacts you find. These remnants remind us of the people of St. Thomas, those who played, worked and lived here.
