Big Creek Dam No. 3, also known as Huntington Lake No. 3, is a captivating structure nestled in the scenic city of Big Creek, California. Completed in 1913, this private dam stands at an impressive height of 165 feet and boasts a multi-arch concrete design, making it a significant landmark in the region. With a primary purpose of hydroelectric power generation, the dam also serves as a recreational area, offering visitors a chance to marvel at its grandeur while enjoying the surrounding natural beauty.

Managed by the Federal Energy Regulatory Commission, Big Creek Dam No. 3 holds a maximum storage capacity of 89,800 acre-feet and covers a surface area of 1,435 acres. It is situated on the Big Creek river and has a drainage area of 80.5 square miles. Despite its age, the dam remains a vital component of the region's water resource infrastructure, providing essential services while posing a high hazard potential due to its condition assessment being unavailable.

While the dam's last inspection was conducted in September 2020, its Emergency Action Plan (EAP) has yet to be prepared, raising concerns about its readiness in the face of potential risks. With a risk assessment rating of high (2) and a hazard potential also categorized as high, there is a pressing need for proactive risk management measures to ensure the safety and security of the surrounding communities in the event of an emergency. Enthusiasts of water resources and climate will find Big Creek Dam No. 3 to be a fascinating subject of study, showcasing the delicate balance between harnessing nature's power for human needs and safeguarding against potential risks and hazards.
