This privately owned earth dam stands at a height of 20 feet and spans 460 feet in length, with a storage capacity of 124 acre-feet and a surface area of 5 acres. The dam also serves recreational purposes, offering opportunities for water-based activities in addition to its irrigation function.
Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level, with a maximum discharge of 35 cubic feet per second in the event of a spill. The spillway, which is uncontrolled and 15 feet wide, helps regulate water levels during periods of excess flow. While the dam has not been rated for its current condition, it is actively monitored for any potential hazards and risks that may arise. The surrounding area of Scotland County, Missouri, benefits from the water resource provided by Gary Anson Dam for agricultural and recreational purposes.
