Big Creek Dam No. 4, nestled in Fresno, California, stands as a testament to early 20th-century engineering excellence. Completed in 1913, this concrete arch dam reaches a height of 75 feet and spans 287 feet across Big Creek. With a storage capacity of 100 acre-feet and a drainage area of 107.1 square miles, the dam primarily serves a hydroelectric purpose, harnessing the power of water to generate energy for the region.

Managed by a private entity, the dam is regulated by both state and federal agencies, ensuring its safety and compliance with rigorous inspection standards. Despite its low hazard potential, the risk assessment for Big Creek Dam No. 4 indicates a very high level of risk, highlighting the critical importance of ongoing monitoring and risk management measures. With a controlled spillway and a maximum discharge capacity of 11,000 cubic feet per second, the dam plays a crucial role in water resource management and climate resilience in the area.

As an iconic feature of the landscape, Big Creek Dam No. 4 not only provides essential hydroelectric power but also serves as a symbol of human innovation and stewardship of natural resources. Its historical significance, combined with its continued operational effectiveness, underscores the vital role of dams in balancing water supply needs, renewable energy production, and environmental sustainability. For water resource and climate enthusiasts, this dam stands as a beacon of progress and a reminder of the delicate balance between human development and environmental protection.
