Abstract :
A COMPREHENSIVE description of the apparatus and methods involved in a cooperative precipitation survey and the results obtained are given in this paper. The scope of the paper is limited principally to the watershed area of the eastern Sierra Nevada range of California, the runoff from which constitutes the chief source of water supply for Reno, Nevada, and environs. Statistical information is presented which reveals the accuracy of predictions based on snow surveys, as compared with actual runoff for various seasons. (A. I. E. E. Paper No. 31 M 4)
