Lower Salmon is a private hydroelectric dam located in Gooding, Idaho, along the Snake River. Built in 1949, this concrete gravity dam stands at 110 feet tall and spans 1200 feet in length. With a normal storage capacity of 10,900 acre-feet, the dam serves multiple purposes, including hydroelectric power generation and recreation. Managed by the Federal Energy Regulatory Commission, Lower Salmon is subject to state regulation and inspection to ensure operational safety and compliance.

The dam's spillway, controlled and 312 feet wide, helps manage water levels and prevent overflow during peak discharge events. With a high hazard potential and a very high risk assessment rating, emergency preparedness and risk management measures are crucial for the surrounding community's safety. Although the condition assessment is not available, the dam's emergency action plan was last revised in April 2021, indicating ongoing efforts to enhance preparedness and response capabilities in case of emergencies.

Lower Salmon's presence not only contributes to the region's energy supply but also offers recreational opportunities for visitors. As a key part of Idaho's water resource infrastructure, the dam exemplifies the balance between harnessing natural resources for power generation and ensuring public safety and environmental stewardship. With its strategic location and vital role in the local ecosystem, Lower Salmon remains a significant feature in Idaho's water management landscape.
