Rockfill Dams: Cogswell And San Gabriel

Features of special interest attending the design, construction, and performance of two rockfill dams 280 and 380 feet in height, more or less, are treated in this paper. Particular attention is paid to such novel features in the design and construction as have proved to be advantageous and successful as well as those which, ingeniously, though they may have been conceived by the designer, were found to be undesirable, if not detrimental. The principal reason for the latter was the fact that conditions in the field failed to fully conform to those anticipated. Through frank discussion thereof it is hoped to avoid repetition and to thereby render a service to the profession.
