Casperson is a private water resource structure located in Franklin, Idaho, serving the primary purpose of irrigation. Built in 1958, this earth-filled dam stands at a height of 22.4 feet and has a storage capacity of 110 acre-feet. The dam spans 425 feet in length and is supported by stone core types with rock and soil foundations.

This low-hazard structure is regulated by the Idaho Department of Water Resources, with regular inspections conducted to ensure its fair condition and operational safety. The dam is equipped with a slide (sluice gate) outlet and an uncontrolled spillway, allowing for a maximum discharge of 71 cubic feet per second. Despite its modest risk assessment rating of moderate (3), Casperson remains a crucial component in the management of water resources in the region, particularly for agricultural irrigation purposes.

With its proximity to unnamed streams and Battle Creek, Casperson plays a vital role in the water infrastructure of the area, supporting the agricultural needs of the community. The dam's location in a remote setting further underscores its importance in sustaining water availability for both human consumption and ecological balance. As climate change continues to impact water resources, structures like Casperson will be key in ensuring sustainable water management practices for future generations.
