Five Mile Erosion Control, located in Idaho's Franklin County, is a privately-owned structure designed to mitigate erosion along the Five Mile Creek and Bear River. Built in 1952, this Earth dam stands at a height of 44.4 feet and has a storage capacity of 250 acre-feet. With a low hazard potential and satisfactory condition assessment, the dam has a controlled spillway with a width of 3 feet and a maximum discharge of 274 cubic feet per second.

Managed by the Idaho Department of Water Resources, Five Mile Erosion Control is regulated, permitted, inspected, and enforced by the state. The structure serves a primary purpose of erosion control and is made of stone core supported by rock and soil foundations. Despite its very high risk assessment due to the potential impact on surrounding areas, the dam's emergency action plan status and risk management measures are currently unknown. With a drainage area of 10.5 square miles and a surface area of 14 acres, this dam plays a crucial role in protecting the local environment and water resources.

Overall, Five Mile Erosion Control serves as a vital infrastructure piece in Idaho's water resource management, providing protection against erosion and ensuring the safety and stability of the surrounding areas. With its history dating back to the 1950s, this structure continues to play a significant role in safeguarding the local ecosystem and maintaining the integrity of the Five Mile Creek and Bear River watersheds. As climate change continues to impact water resources, the upkeep and maintenance of structures like Five Mile Erosion Control are essential in mitigating potential risks and preserving the natural environment for future generations.
