Managed by the Bureau of Land Management, this Federal-owned structure stands at a hydraulic height of 22 feet and a structural height of 28 feet, with a length of 531 feet and a storage capacity of 28 acre-feet. Despite its low hazard potential, the dam's condition assessment is rated as poor, indicating a need for maintenance and repairs.
With a maximum storage capacity of 14.9 acre-feet and a surface area of 5.5 acres, South Fork Dam serves as a vital infrastructure for water resource management in the region. The dam features an uncontrolled spillway type with a width of 2 feet, ensuring effective flood control and sediment retention. While the dam's risk assessment is moderate, it is essential for stakeholders to prioritize regular inspections and maintenance to uphold its structural integrity and prevent any potential hazards to the surrounding area.
As a key component of the water management system in Wyoming, South Fork Dam plays a crucial role in safeguarding the environment and local communities from the impacts of extreme weather events and climate change. With Liz Cheney (R) representing the district, continued support and investment in dam safety and maintenance are essential to ensure the long-term resilience and sustainability of this critical infrastructure for water resource enthusiasts and climate advocates alike.
