Cascade is a federal hydroelectric dam located in Idaho, specifically in the city of Cascade along the North Fork Payette River. Built in 1948 by the Bureau of Reclamation, Cascade serves multiple purposes including hydroelectric power generation and irrigation. With a dam height of 110 feet and a storage capacity of 860,000 acre-feet, Cascade covers a surface area of 27,700 acres and has a maximum discharge of 12,500 cubic feet per second.

This rockfill dam has a controlled spillway with a width of 42 feet and is regulated by the Bureau of Reclamation. The dam's hazard potential is classified as high, with a very high risk assessment score. Despite its age, Cascade's condition assessment is currently listed as not available, indicating a need for further inspection and evaluation. The Emergency Action Plan (EAP) for Cascade has not been updated recently, raising concerns about the readiness and response protocols in case of emergencies.

Water resource and climate enthusiasts can appreciate the significance of Cascade as a key infrastructure for water management in Idaho. As a critical component of the region's hydroelectric and irrigation systems, Cascade represents a complex engineering feat with implications for water supply, energy production, and environmental stewardship. Continued monitoring and maintenance of Cascade are essential to ensure the safety and sustainability of this important water resource infrastructure.
