Anderson Ranch is a federal-owned dam located in Reclamation Village, Idaho, along the South Fork Boise River. Built in 1946 by the Bureau of Reclamation, this earth dam stands at 456 feet high and serves multiple purposes including flood risk reduction, hydroelectric power generation, and irrigation. With a storage capacity of 503,500 acre-feet and a normal storage of 464,216 acre-feet, Anderson Ranch plays a crucial role in water management and resource allocation in the region.

The dam's spillway, with a controlled design and a width of 50 feet, helps manage water flow and prevent flooding during periods of high discharge. The hazard potential of Anderson Ranch is classified as high, and a risk assessment has deemed it to have a very high risk level. Despite its age, the dam's condition assessment is currently not available, highlighting the need for ongoing monitoring and maintenance to ensure its continued safety and effectiveness in water resource management.

As a key component of the Bureau of Reclamation's operations, Anderson Ranch demonstrates the intricate balance between water resource management, infrastructure development, and environmental conservation. Its location in a scenic area surrounded by the natural beauty of Idaho makes it not only a critical piece of infrastructure but also a symbol of the complex relationship between human needs and environmental stewardship in the face of changing climate dynamics.
