The Gene Hertzog Professional Papers (approximately 1930-2015) are comprised of photographs, slides, transparencies, publications, video cassettes, correspondence, and digital files spanning Gene Hertzog's working years with the United States Army, the Bureau of Reclamation, and as a freelance photographer and videographer based in Southern Nevada, New Mexico, and Washington state. The collection documents the complicated infrastructure required to supply water to the Las Vegas Valley and includes still and moving images of the Springs Preserve, Lake Mead National Recreation Area, the Colorado River, and the Columbia Basin. The majority of the collection comes from Hertzog's time as a regional photographer for the Bureau of Reclamation and offers a unique glimpse into the Bureau's work in Southern Nevada, the southwest, and the Pacific Northwest from the 1950s to the mid-1990s.
