Brownlee Dam, located on the Snake River in Oxbow, Oregon, is a rockfill dam with a primary purpose of hydroelectric power generation. Completed in 1958, it stands at a height of 395 feet and has a storage capacity of 1,470,000 acre-feet. The dam also serves purposes such as flood risk reduction, navigation, and recreation, making it a crucial infrastructure for the region.
Managed by the Federal Energy Regulatory Commission, Brownlee Dam has a controlled spillway and seven Tainter gates for water discharge. With a high hazard potential and a very high risk assessment rating, the dam plays a vital role in water resource management and climate adaptation in the area. Despite its importance, the condition assessment of the dam is currently not available, highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality.
With its strategic location and multiple functions, Brownlee Dam is a key player in the water resource and climate landscape of Idaho and Oregon. As climate change continues to impact water availability and extreme weather events, the dam's role in flood control, energy production, and wildlife conservation becomes increasingly critical. As such, continued investment in monitoring, maintenance, and risk management measures will be essential to safeguard the dam's operation and the surrounding communities in the face of evolving climate challenges.
