South Fork Diversion, located in Woodleaf Powerhouse, California, is a significant hydroelectric structure on the South Fork Feather River. Constructed in 1961, this concrete dam stands at a height of 60 feet and has a hydraulic height of 46 feet. With a storage capacity of 87 acre-feet and a maximum discharge of 20,700 cubic feet per second, the dam serves multiple purposes including hydroelectric power generation, irrigation, and water supply for the surrounding area. Managed by a public utility, the dam is regulated and inspected by various state and federal agencies, including the Department of Water Resources (DWR) and the Federal Energy Regulatory Commission (FERC).

The dam's spillway is uncontrolled with a width of 180 feet, and its hazard potential is categorized as low. Despite its moderate risk assessment, the condition assessment of South Fork Diversion is currently marked as not available, highlighting the need for ongoing monitoring and maintenance. While the dam has not undergone any modifications in recent years, emergency action plans (EAP) are in place, with the last revision made in November 2020. With its strategic location and critical role in water resource management, South Fork Diversion remains a key infrastructure for ensuring the sustainable use of water and energy resources in the region.

Overall, South Fork Diversion stands as a testament to Bechtel's design expertise and the collaborative efforts of various stakeholders in the water and energy sectors. As climate change continues to impact water resources, the role of such structures in providing renewable energy and water supply becomes increasingly crucial. With its historical significance and operational efficiency, South Fork Diversion serves as a model for sustainable water management practices in the face of evolving climate challenges.
