Humeston Reservoir Dam, located in Chariton, Iowa, is a vital water resource infrastructure primarily owned and regulated by the local government. Completed in 1916, this earth dam stands at a height of 31 feet and has a length of 670 feet, providing essential water supply for the region. With a storage capacity of 900 acre-feet, it serves both recreational and water supply purposes, covering a surface area of 37.4 acres and draining a 1.02 square mile watershed area.

Despite its historical significance, the dam's current condition assessment is poor, with a significant hazard potential. The last inspection in August 2019 revealed the need for improvements to ensure public safety and water resource management. The dam's spillway is uncontrolled with a width of 18 feet, posing a potential risk in cases of high discharge. The risk assessment categorizes the dam as moderate, indicating the need for risk management measures to address safety concerns and ensure its long-term sustainability.

Given its critical role in water supply and recreational activities, the Humeston Reservoir Dam requires immediate attention to address its poor condition and mitigate potential hazards. Collaborative efforts between local and state regulatory agencies, such as the Iowa DNR, are essential to implement necessary upgrades and ensure the dam's compliance with safety standards. Climate and water resource enthusiasts are encouraged to monitor the dam's risk management measures and support initiatives aimed at preserving this important infrastructure for future generations.
