Abstract:

The U.S. Bureau of Reclamation takes a look at several new ways of building old dams for maximum flooding. A labyrinth spillway was built at Ute Dam near Logan, N.M. to increase reservoir storage and spillway discharge capacity. In Northern Montana, using patented reinforced earth retaining walls to raise Lake Sherburne Dam's crest cut construction time. The Bureau also applied new materials for dam and spillway repair, and studied the use of auxiliary spillways with fuse plugs as cost-efficient alterntatives for passing flows from large floods with a remote chance of occurring.
