Hyrum Dike, located in Cache County, Utah, along the Little Bear River, is a federal-owned structure managed by the Bureau of Reclamation. Completed in 1935, this earth dam stands at 18 feet high and serves primarily for irrigation purposes, with a storage capacity of 18,685 acre-feet. Stretching 850 feet in length and covering a surface area of 480 acres, Hyrum Dike plays a crucial role in water supply management in the region.

Notable for its high hazard potential, Hyrum Dike lacks a spillway and is categorized as a high-risk structure. Despite its age, the condition assessment of the dam is currently not available, raising concerns about its long-term resilience. With the last inspection conducted in August 2020 and a designated inspection frequency of one year, the structure is closely monitored by the Bureau of Reclamation to ensure public safety and water resource sustainability.

As climate change poses new challenges to water resource management, the importance of structures like Hyrum Dike in regulating water flow and providing essential irrigation services cannot be overstated. With ongoing risk assessments and emergency action planning, efforts are being made to mitigate potential hazards and safeguard the surrounding communities. Hyrum Dike stands as a testament to the intricate balance between human infrastructure and natural resources, highlighting the critical role of water management in the face of a changing climate.
