Pelton, located in Warm Springs, Oregon, is a captivating hydroelectric dam situated on the Deschutes River. Constructed in 1957, this arch-type dam stands at a height of 204 feet, with a hydraulic height of 195 feet, making it a significant structure for water resource and climate enthusiasts. With a storage capacity of 31,800 acre-feet and a maximum discharge of 23,500 cubic feet per second, Pelton plays a crucial role in water management and renewable energy production in the region.

The dam's primary purpose is hydroelectric power generation, but it also offers recreational opportunities for visitors. Its controlled spillway, with a width of 76 feet, ensures safe water release during high-flow events. Despite its high hazard potential, Pelton has not undergone recent condition assessments, highlighting the need for continued monitoring and maintenance to ensure its safety and resilience to potential risks. With the Federal Energy Regulatory Commission overseeing its regulation and inspections, Pelton remains an essential infrastructure for sustainable water resource management and climate mitigation efforts in Oregon.

Pelton's strategic location, structural design, and operational capacity make it a key player in the region's water resource and climate resilience strategies. As a critical piece of the Deschutes River ecosystem, Pelton provides not only clean energy but also valuable recreational opportunities and flood control measures. With its high hazard potential and very high risk assessment rating, ongoing monitoring and risk management measures are essential to safeguarding this vital infrastructure for future generations. As climate change impacts continue to affect water resources, Pelton's role in sustainable water management and renewable energy production will only grow in importance.
