Sherwood Dam, known also as Lake Sherwood Dam,[2] Alturas Dam, and Potrero Dam, is a 270-foot-long (82 m) concrete arch dam in the Santa Monica Mountains near Thousand Oaks, California. Completed in 1904, its construction led to the creation of the 165-acre (67 ha) Potrero Lake (since renamed Lake Sherwood)[3] over the following winter. It was the first reservoir of its size in the area, and remains one of the oldest standing dams in California.[1]
