The dam is primarily an earth type structure with a height of 23 feet and a length of 370 feet, providing a maximum storage capacity of 83 acre-feet. Situated on Grassy Creek, the dam helps regulate water flow and minimize the risk of flooding, benefiting the local community and surrounding wildlife.
Despite its low hazard potential and moderate risk assessment, Grassy Creek Watershed Dam G-48 has not been rated for its condition assessment. The dam features an uncontrolled spillway and outlet gates, with a hydraulic height matching its structural height of 27 feet. With a drainage area of 121.6 square miles, the dam plays a crucial role in managing water resources in the region. While it is not currently under state jurisdiction or regulation, the dam's construction and operation are overseen by the USDA NRCS, highlighting the importance of federal agencies in managing water infrastructure for flood control and environmental protection in Missouri.
