Designed by USDA NRCS, this earth dam stands at a height of 21 feet and serves the primary purpose of grade stabilization. With a storage capacity of 120 acre-feet and a drainage area of 200 square miles, this dam plays a crucial role in managing water resources in the area. The dam's spillway, with a width of 70 feet, is uncontrolled, and the hazard potential is rated as low.
Situated on TR-WILLOW CREEK, this structure is part of the Rock Island District and is not regulated by the state. With a moderate risk assessment rating, the dam has not been inspected recently and is currently not rated for its condition. Despite the lack of state oversight, the dam continues to provide valuable grade stabilization and water management benefits to the surrounding area. Enthusiasts interested in water resources and climate will find the design and purpose of Grindstone-Lost-Muddy Watershed Dam C-28 fascinating, as it highlights the importance of earth dams in maintaining a sustainable water supply in Missouri.
