This LSTA-grant funded digital collection documents the historic role of water resource management in Southern Nevada. From the natural springs that attracted the earliest inhabitants and travelers, to the wells that supported early town development, to the massive federal reclamation projects that dammed the Colorado River to irrigate the California and Arizona deserts, water ruled. The basic issues of water use—its quantity, quality, and allocation—still dominate policy and politics in Nevada and the Southwest. This collection offers an incredibly diverse range of media. It brings together nearly 1,300 pictures, technical reports, maps, legislation, letters, contracts, books, newspapers, postcards, licenses, meeting minutes, charts, and documents from the University Libraries’ Institutional Repository. Also included are several Primary Source sets designed to immediately connect educators with historical materials. These sets can be used to supplement teaching in a wide range of disciplines.
