Twin Lakes South is a privately owned irrigation dam located in Bear River Confluence, Idaho. Built in 1920, this earth dam stands at a height of 35.5 feet and has a hydraulic height of 31 feet, with a storage capacity of 14,000 acre-feet. Despite its age, the dam's condition is assessed as satisfactory, with a high hazard potential due to its location near the Deep Creek and Bear River.

The dam does not have a spillway, and water is controlled through slide gates. The last inspection in November 2020 deemed the structure to be in good condition. However, due to its high-risk potential, it is crucial for regulatory agencies like IDWR to continue regular inspections and maintenance to ensure the safety of surrounding communities and the integrity of the dam. Twin Lakes South serves a vital purpose in irrigation, making it a key water resource in the area.

With its historical significance and essential role in water management, Twin Lakes South highlights the intersection of water resource management and climate resilience. As climate change poses increasing challenges to water availability and infrastructure safety, the proper regulation and maintenance of dams like Twin Lakes South become even more critical. By staying vigilant in monitoring and addressing potential risks, stakeholders can ensure the continued functionality and safety of this important irrigation structure for years to come.
