Langerak Dam, located in Marion, Iowa, is a privately owned earth dam that was completed in 1986 for the primary purposes of fire protection, stock, and small fish pond. The dam stands at a height of 32 feet and has a length of 480 feet, creating a reservoir with a normal storage capacity of 46 acre-feet and a maximum storage of 102 acre-feet. With a surface area of 6.3 acres and a drainage area of 0.39 square miles, the dam serves as a vital water resource for the area.

Managed by the Iowa Department of Natural Resources, Langerak Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. Despite its low hazard potential, a moderate risk assessment indicates the necessity of implementing risk management measures in the future. The dam's spillway type is uncontrolled, and there are no outlet gates or associated structures. The location along the TR- VAN ZANTE CR. stream in South Skunk River adds to the significance of Langerak Dam as a key component of the local water infrastructure.

For water resource and climate enthusiasts, Langerak Dam presents a unique opportunity to explore the intersection of human engineering and natural ecosystems. Its construction and maintenance reflect the ongoing efforts to balance water management needs with environmental sustainability. As a pivotal structure in the Kansas City District, Langerak Dam serves as a testament to the collaborative efforts between private owners and state agencies to protect and utilize water resources effectively.
