This private-owned earth dam stands at a height of 31 feet and spans 400 feet in length, with a storage capacity of 578 acre-feet. Despite its low hazard potential, the dam is regulated by the Illinois Department of Natural Resources and undergoes regular state inspections and enforcement to ensure its structural integrity.
The dam features an uncontrolled spillway with a width of 75 feet and operates with uncontrolled outlet gates. Its primary purpose and design are focused on flood risk reduction, effectively mitigating the impact of high water levels in the region. Despite its moderate risk assessment rating, the dam currently lacks a comprehensive emergency action plan and condition assessment, highlighting areas for potential improvement in its risk management measures. With its strategic location and design, Little Cache Structure 5 Dam stands as a vital infrastructure supporting water resource management and climate resilience efforts in the area.
