Directory of Drowned Towns

See below for a growing and evolving list of communities in the American West that may have been displaced and/or disappeared by river development projects. Please note: this list is a product of tips, suggestions, and bits & pieces gathered from the internet, and so some of these towns may not in fact have been inundated by dams and their reservoirs. That’s part of the point of this project — to identify real and truly drowned towns.

This list is woefully incomplete — please help! Do you know of other such drowned towns? Do you know more about these towns? Were these towns not actually drowned by river development projects? Share your knowledge with The Atlas of Drowned Towns!
