Englebright Dam is a 280 ft (85 m) high variable radius concrete arch dam on the Yuba River in the Sacramento River Basin, located in Yuba and Nevada counties of California, United States.
The dam was constructed in 1941 for the primary purpose of trapping sediment derived from anticipated hydraulic mining operations in the Yuba River watershed.
Hydraulic mining in the Sierra Nevada was halted in 1884 but resumed on a limited basis until the 1930s during the great depression under the California Debris Commission.
Constructed for the storage of hydraulic gold mining debris, Englebright Dam is a concrete arch structure.
The dam is in the steep Yuba River gorge known as the Narrows, holding back a 9-mile-long (14 km) lake with a surface area of 815 acres (3.30 km2; 330 ha).
