Magic Spillway


May 4, 2024

Magic Spillway, located in Shoshone, Idaho, is a privately owned concrete dam completed in 1910 for hydroelectric and irrigation purposes on the Big Wood River. With a height of 50 feet and a spillway width of 1200 feet, this structure has a storage capacity of 195,000 acre-feet and a maximum discharge of 100,000 cubic feet per second. The dam is regulated by the Federal Energy Regulatory Commission and inspected regularly to ensure its safety and compliance with state regulations.

Despite its age, Magic Spillway remains a critical infrastructure for water resource management in the region, with a high hazard potential due to its location and design. The dam's risk assessment has been classified as very high, emphasizing the importance of proper maintenance and emergency preparedness. While its condition assessment is currently not available, efforts are being made to ensure that the spillway meets guidelines for emergency action plans and risk management measures.

As a key component in the water resources network of Blaine County, Idaho, Magic Spillway serves as a reminder of the intersection between water infrastructure, climate resilience, and regulatory oversight. Its history and operational significance make it a focal point for enthusiasts and professionals interested in hydroelectric power generation, dam safety, and sustainable water management practices.
