Sinaloa Lake, located in Ventura, California, is a privately owned dam with a primary purpose of flood risk reduction. Completed in 1925, this earth dam stands at 30 feet high and spans 800 feet in length, creating a storage capacity of 205 acre-feet. The lake covers a surface area of 15 acres and is fed by Tr Arroyo Simi, with a drainage area of 0.31 square miles.
Managed by the California Department of Water Resources (DWR) for dam safety, Sinaloa Lake poses a high hazard potential but has been assessed as satisfactory in condition. Regular inspections, with a frequency of one per year, ensure the structure's integrity. The dam is also equipped with emergency action plans to mitigate risks and protect surrounding communities in case of an emergency. Despite its primary purpose for flood risk reduction, the lake also serves irrigation, recreation, and water supply needs in the region.
Enthusiasts of water resources and climate will find Sinaloa Lake an intriguing example of human-engineered infrastructure in the face of natural challenges. Its historical significance, combined with its multiple uses and the regulatory oversight it falls under, make it a focal point for understanding the intersection of water management, safety, and community resilience in the state of California.
