The dam is situated along the TR-Lame Jones Creek and serves as a vital water resource for agricultural purposes in the area. With a height of 25 feet and a length of 350 feet, the dam has a storage capacity of 90 acre-feet, providing a reliable water source for irrigation needs.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), 7-Up Sea is regulated, inspected, and enforced to ensure its structural integrity and operational efficiency. The dam has a low hazard potential and is not currently rated for its condition assessment. With a maximum discharge capacity of 600 cubic feet per second and a spillway width of 60 feet, the dam is designed to manage water flow effectively and mitigate potential risks associated with heavy precipitation events.
Despite not being rated for condition assessment, 7-Up Sea plays a crucial role in supporting agricultural activities in the region. With its state-regulated status and ongoing inspection and enforcement measures, the dam exemplifies responsible water resource management practices in the face of changing climate conditions. Enthusiasts interested in water resources and climate resilience will find 7-Up Sea to be a fascinating case study in sustainable irrigation infrastructure development and maintenance.
