St. Thomas, Nevada

St. Thomas, Nevada is a ghost town in Clark County, Nevada, near where the Muddy River flows into the Colorado River. St. Thomas was purchased by the US Federal Government and abandoned as the waters of Lake Mead submerged the town in the 1930s. However, as the level of Lake Mead dropped in the 2000s, the ruins of the town resurfaced. It is now located within the Lake Mead National Recreation Area.

The town was founded by Mormon settlers led by Thomas Smith in 1865. With a population of about 500 at its peak, St. Thomas became an established town of farms and businesses, and was at one point the county seat of Pahute County. The Mormons abandoned St. Thomas in February 1871, as a land survey shifted the state line of Nevada one degree longitude to the east, placing all of the Mormon settlements known as the Muddy Mission in Nevada instead of Arizona or Utah. The state of Nevada then attempted to collect taxes for previous years payable only in gold from the residents. They chose to leave without paying in 1871. The Mormons moved to Utah, where many of them founded new towns in Long Valley (present day Glendale, Orderville, and Mount Carmel).

When the Mormons left in 1871, others claimed their abandoned properties. One of the few to remain was Daniel Bonelli of St. Thomas, who farmed, mined and owned Bonelli's Ferry on the Colorado River at Junction City later Rioville. After being deserted by most of its first settlers, new Mormon settlers came to the St. Thomas and other places in the area in the 1880s.

The construction of Hoover Dam and the resulting rise in the waters of the Colorado River forced the abandonment of the town, with the last resident, Hugh Lord, leaving June 11, 1938.
