The Western Waters Digital Library has a bunch of resources on Lake Mead from a variety of institutions. Here is a sampling of the type of information you can find:

Statement before the Parks and Recreation subcommittee on the Senate Interior and Insular Affairs Committee, on recreation responsibilities, from Digital Collections of Colorado.

Photograph of U. S. Navy deep-sea divers conducting Lake Mead sedimentation survey, circa 1948 from the University of Nevada, Las Vegas.

We’ve gone live with the new design for the Western Waters Digital Library! The redesign, done by Leah Martin of the University of Utah’s J. Willard Marriott Library’s Discovery and Web Development group is designed to look great on browsers with varying screen sizes, including tablets and smartphones. We also have a new exhibits page to highlight, with contributions from Southern Methodist University’s DeGolyer Library, University of Washington Libraries, and WWDL maps from the Digital Scholarship Lab at the J. Willard Marriott Library. Thanks to everyone involved in the redesign!

Today we are featuring an item from Utah State University’s Digital Repository by David G Tarboton, “Measurements and Modeling of Snow Energy Balance and Sublimation from Snow

From the description, “Snow melt runoff is an important factor in runoff generation for most Utah rivers and a large contributor to Utah’s water supply and periodically flooding. The melting of snow is driven by fluxes of energy into the snow during warm periods. These consist of radiant energy from the sun and atmosphere, sensible and latent heat transfers due to turbulent energy exchanges at the snow surface and a relatively small ground flux from below. The turbulent energy exchanges are also responsible for sublimation from the snow surface, particularly in arid environments, and result in a loss of snow water equivalent available for melt. The cooling of the snowpack resulting for sublimation also delays the formation of melt runoff. This paper describes measurements and mathematical modeling done to quantify the sublimation from snow.”
