Wehrspann Dam, also known as Wehrspann Lake, is a federal-owned structure located in Sarpy, Nebraska, near the city of Omaha. Completed in 1983 by the US Army Corps of Engineers, this earth dam serves primarily for flood risk reduction but also provides benefits for fish and wildlife, recreation, and water storage. Standing at a structural height of 87 feet with a hydraulic height of 82 feet, the dam has a storage capacity of 17,164 acre-feet and covers a surface area of 246 acres.

Managed by the US Army Corps of Engineers, Wehrspann Dam is equipped with an uncontrolled spillway and has a maximum discharge capacity of 17,500 cubic feet per second. The dam poses a high hazard potential, and regular inspections are conducted to ensure its safety and effectiveness in managing flood risk. The Corps implements various risk management measures, such as monitoring dam conditions, prioritizing maintenance activities, and engaging with local emergency managers to prepare for potential emergencies. Despite the risks associated with dams and potential flooding events, efforts are continually made to mitigate these risks and ensure public safety.

In the event of severe weather or increased water inflow, the dam may release water to manage levels and prevent structural issues. The Corps works diligently to address all types of flood risk associated with the dam and regularly updates emergency action plans to be prepared for any potential emergencies. With a focus on proactive risk management and community engagement, Wehrspann Dam plays a crucial role in protecting the surrounding area from flooding and ensuring the safety of both the dam and the community it serves.
