The former Mormon settlement of St. Thomas, Nevada, is reappearing from the depths of Lake Mead as water levels continue to recede.
The reemergence of the town serves as a visible indicator of the severe drought and water usage affecting the Colorado River reservoir. As the shoreline retreats, the remnants of a community once lost to infrastructure development are becoming accessible again.
Founded in 1865 [1], St. Thomas was a thriving settlement until the construction of the Hoover Dam created Lake Mead. The resulting reservoir flooded the valley, submerging the town beneath 60 feet of water [2]. Reports on the exact timing of the flooding vary, with some records citing 1935 [1] and others citing 1938 [1].
For decades, the town remained a ghost settlement hidden by the reservoir. However, the decline of Lake Mead has brought the site back to the surface. The receding waters have exposed the foundations and structures of the community, a process that became more pronounced in 2024 [1].
The town's disappearance was a direct consequence of the dam's creation, which was designed to provide water and power to the Southwest. The current visibility of St. Thomas highlights the volatility of the region's water security. While the sight of the ghost town provides a glimpse into Nevada's pioneer history, it also underscores the environmental pressures facing the Colorado River system.
“The former Mormon settlement of St. Thomas, Nevada, is reappearing from the depths of Lake Mead.”
The resurfacing of St. Thomas is not merely an archaeological curiosity but a symptom of a systemic hydrological crisis. The exposure of a town that was submerged for nearly 90 years demonstrates the scale of water loss in Lake Mead, reflecting the long-term impact of climate change and unsustainable water consumption in the American Southwest.
