The pond serves multiple purposes, including flood control and water storage, with a maximum capacity of 21 acre-feet and a normal storage of 13 acre-feet. Situated on the Sand Branch tributary of Little Bear River, the dam spans 200 feet in length and stands at a height of 29 feet, with a spillway width of 10 feet for uncontrolled water release.
Despite its age, Fraley Pond is state-regulated and regularly inspected by the Illinois Department of Natural Resources to ensure its structural integrity and safety. The dam has a moderate hazard potential, and while the condition assessment is currently not available, the risk management measures are in place to address any potential issues. With its critical role in water resource management and climate adaptation, Fraley Pond represents a significant infrastructure asset in the St. Louis District, contributing to the overall water security of the region.
