Idaho Falls Upper Powerhouse Dam No 2, also known as Upper Power Dam, is a concrete multi-arch dam located in Bonneville, Idaho. Completed in 1982, the dam stands at a height of 36.5 feet and has a hydraulic height of 29.7 feet. It serves the primary purpose of hydroelectric power generation and is owned by a public utility in Idaho Falls. With a normal storage capacity of 424 acre-feet and a drainage area of 9,050 square miles, the dam plays a significant role in water resource management in the region.

Situated on the Snake River and Columbia River, the Idaho Falls Upper Powerhouse Dam No 2 has a spillway width of 40 feet and a maximum discharge capacity of 13,500 cubic feet per second. Despite its low hazard potential, the dam's risk assessment is rated as very high, warranting proper risk management measures. The dam is regulated by the Idaho Department of Water Resources and undergoes regular inspections to ensure its structural integrity and operational safety. With its vital role in hydroelectric power generation and water storage, the dam remains a key infrastructure for both the local community and the broader region.

Overall, the Idaho Falls Upper Powerhouse Dam No 2 stands as a crucial piece of infrastructure in Idaho's water resource management and renewable energy production efforts. Its strategic location on the Snake River and Columbia River, coupled with its significant storage capacity and high-risk assessment, underscores the importance of proper maintenance and monitoring. As climate change continues to impact water resources, the dam's role in ensuring a reliable water supply and sustainable energy generation becomes increasingly vital for the resilience of the region's water and energy systems.
