The Soulen Main Dam, located in remote Idaho, was completed in 1935 for the primary purpose of irrigation. This earth dam, with a height of 18.4 meters and a length of 680 meters, holds back the waters of South Crane Creek and Crane Creek to provide water for agriculture in the region. The dam has a storage capacity of 630 acre-feet and covers a surface area of 113 acres.

Despite being regulated by the Idaho Department of Water Resources, the dam has a significant hazard potential and is classified as being in fair condition as of the last inspection in 2017. With a high risk assessment level, it is essential for the dam's operators to closely monitor its safety and maintenance to prevent any potential failures. The dam does not have a spillway, making proper management and regular inspections even more crucial for the safety of downstream communities and ecosystems.

For water resource and climate enthusiasts, the Soulen Main Dam serves as a critical infrastructure for supporting agricultural activities in the region. Its history, design, and current condition highlight the importance of sustainable water management practices and the need for ongoing monitoring and maintenance to ensure the safety and resilience of dams in the face of changing environmental conditions and potential hazards.
