With a height of 27 feet and a length of 600 feet, the dam has a storage capacity of 81.14 acre-feet and serves the primary purpose of grade stabilization. Despite its low hazard potential and moderate risk assessment, the dam is not regulated or inspected by the state, presenting some challenges in terms of oversight and maintenance.
The dam features an uncontrolled spillway and outlet gates, with a maximum discharge of 18.4 cubic feet per second. It covers a surface area of 7 acres and drains a watershed area of 422.4 acres. Although it has not been rated for its condition assessment, Luetkemeyer Dam remains a critical infrastructure for managing water resources in Ralls County. Its location within the St. Louis District and under the supervision of the Natural Resources Conservation Service underscores its importance for local water management and climate resilience efforts.
As a key component of the water infrastructure in Missouri, Luetkemeyer Dam plays a vital role in flood control and water supply management. Its construction and design by the USDA NRCS reflect a commitment to sustainable water resource development and environmental stewardship. Moving forward, continued monitoring and maintenance of the dam will be essential to ensure its long-term functionality and resilience in the face of changing climate patterns and water management challenges.
