Constructed in 2004 by designers Vance & Hochstetler, this private-owned Earth dam stands at a height of 32 feet and spans 730 feet in length. The dam has a storage capacity of 92 acre-feet, with a normal storage level of 43 acre-feet, covering a surface area of 6.2 acres and draining a 0.19 square mile watershed.
Despite its primary purpose for recreation, Oak Hill Plantation Dam holds a significant hazard potential, with a moderate risk assessment rating of 3. The dam is state-regulated by the Iowa Department of Natural Resources, ensuring inspection, enforcement, and permitting compliance. The spillway is uncontrolled, with a width of 2 feet, and the dam is built on a soil foundation. While the dam's condition assessment is not rated, its risk management measures and emergency action plan status are currently unclear.
The dam's strategic location and design make it a notable feature in the water resource and climate community, attracting enthusiasts and researchers alike. Its association with the Rock Island District and proximity to De Soto further highlight Oak Hill Plantation Dam's significance in the region. With its unique characteristics and operational complexities, this dam presents a fascinating case study for those interested in the intersection of water management, infrastructure, and environmental risk assessment.
