The U.S. Army Corps of Engineers owns and operates a large portfolio of dams that provide a variety of critical benefits to society, including flood risk management, navigation, hydropower and recreation. However, there are risks to life and property if a dam were to fail. The Corps monitors the condition and performance of these dams, using assessments and evaluations to provide information about the structures.
The Portland District, as part of its Dam Safety program, monitors the condition and performance of the structures owned and operated by the District. These structures are within the Columbia, Willamette and Rogue river basins, and are well-designed, well-constructed and are functioning as intended. There is no evidence to suggest an emergency situation exists, or is about to occur.
- 19 dams
- Mount St. Helens sediment retention structure
- Five navigation locks
- 13 hydropower plants
It is important that residents who live downstream from a dam are aware of the potential consequences should the dam breach, not perform as intended, or experience major spillway or outlet works flows.
