Nixon No 2, also known as Lower Nixon Dam, is a private-owned structure located in Boundary, Idaho, along Springs Bane Creek. This earth dam, primarily used for irrigation purposes, stands at a height of 12.7 meters with a storage capacity of 80.3 acre-feet. Despite its low hazard potential, the dam is in poor condition, as indicated by a 2016 assessment.

The dam features an uncontrolled spillway with a width of 6 meters and outlet gates consisting of slide (sluice gate) mechanisms. While it has not undergone significant modifications since its construction, Nixon No 2 is subject to state regulation, inspection, and enforcement by the Idaho Department of Water Resources. The risk assessment for the dam is rated as moderate (3), highlighting the need for ongoing monitoring and potential management measures to ensure its safety and functionality in the face of evolving climate conditions.

For water resource and climate enthusiasts, Nixon No 2 serves as a reminder of the intricate infrastructure supporting agricultural activities in the region and the importance of maintaining and upgrading such systems to withstand the impacts of changing environmental conditions. As a private dam under state jurisdiction, its management and upkeep are crucial for both water supply reliability and the safety of downstream communities. With its location in a remote area and limited associated structures, Nixon No 2 stands as a testament to the intersection of water resource management, infrastructure resilience, and climate adaptation in the face of potential hazards.
