Purposes of study and report: This report presents the results of a continuing study conducted by the U.S. Geological Survey in cooperation with the Denver Board of Water Commissioners. Purposes of the study are: (l) To define the amounts of net evaporation losses from the Denver storage reservoirs; and (2) to conduct experiments for improving methods for measuring evaporation, particularly at reservoirs at high elevations.

From Summary: "The transport-depletion data obtained by the Southern Research Institute and by the Bureau of Reclamation at Denver, Colorado and at Webster, South Dakota, was reviewed. This data review made it possible to develop a design methodology for the pilot plant, and to identify the additional data required to adequately predict the performance of a transport-depletion stack."
