Black Hawk Lake Dam, located in Lake View, Iowa, was completed in 1916 and serves as a critical infrastructure for flood risk reduction along the Wall Lake Outlet. The dam is classified as an earth dam, standing at a height of 12 feet and with a storage capacity of 10,500 acre-feet. With a surface area of 920 acres and a drainage area of 23.4 square miles, the dam plays a crucial role in managing water flow and reducing flood risks in the region.

Managed by the Iowa Department of Natural Resources, Black Hawk Lake Dam is regulated and inspected regularly to ensure its structural integrity and functionality. The dam has a significant hazard potential, but its condition assessment in 2019 deemed it satisfactory. Despite the moderate risk level associated with the dam, it continues to meet guidelines for emergency action preparedness and risk management measures.

With its primary purpose being flood risk reduction, Black Hawk Lake Dam not only safeguards the local community from potential flooding but also provides recreational opportunities for visitors. The dam's uncontrolled spillway, with a width of 38 feet, contributes to its efficient water management system. Overall, Black Hawk Lake Dam stands as a vital component in the water resource and climate management efforts in the region.
