Dam profile
NID height · 32 ft32 ft tall and 280 ft long, taller than 74% of U.S. dams with a recorded height. Height is drawn to scale against a two-story house, about 25 ft; the profile is a generic embankment section and the water level is illustrative.
About Silver Lake
The primary purpose of Silver Lake is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by El Dorado Irrigation District (private). It impounds the Silver Fork American River near Kyburz.
The dam stands 32 feet tall and stretches 280 feet across, creates a reservoir covering 525 acres, has a maximum storage capacity of 13,130 acre-feet, and collects water from a drainage area of 15 square miles. Completed in 1876, the structure is over a century old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 08/23/2023.
