SMUD owns and operates 13 dams. They were designed starting in the late 1950s and constructed 1961 through 1970. Elevations of these dams range from 200 ft in the Central Valley to 6,500 ft in the Sierra Nevada; they are of earthen and concrete construction; and they range in height from 20 ft to 450 ft. Several dams include appurtenant structures such as spillway gates and saddle dikes. In descending order of elevation these dams are: • Rubicon Dam • Buck Island Dam • Loon Lake Dam • Gerle Dam • Robbs Peak Dam • Ice House Dam • Union Valley Dam • Junction Dam • Camino Dam • Brush Creek Dam • Slab Creek Dam • Chili Bar Dam • Rancho Seco Dam Based on past efforts, some of the types of detailed engineering and design could include the following examples.
