Rancho Seco Nuclear Generating Station

Rancho Seco Nuclear Generating Station is a decommissioned nuclear facility located in Herald, California, situated on a large property in the Sacramento Valley. The site now includes a recreational lake formed from the cooling system, while a designated section continues to store low-level radioactive materials.

The Sacramento Municipal Utility District built and operated this facility beginning in 1974, but a public referendum in 1989 resulted in its permanent shutdown. This vote reflected growing public concern about nuclear power and marked a turning point in California's energy policy.

The facility stands as a symbol of California's shifting energy policies and public attitudes toward nuclear power generation during the late 20th century.

The site is open to the public for recreation including hiking, biking, and fishing around the lake. Visitors should follow posted signs and guidelines, especially when near the restricted areas that contain radioactive materials.

The facility's massive cooling towers remain standing after decommissioning and have become distinctive landmarks visible from across the surrounding farmland. These structures attract photographers and artists interested in industrial remains.
