League Dam, located in Douglas, Nebraska, is a privately owned structure designed for flood risk reduction on the Elkhorn River. Completed in 1960, this earth dam stands at a height of 29 feet and spans 260 feet in length, with a storage capacity of 17.6 acre-feet. Despite its significant hazard potential, the dam's condition assessment is currently rated as poor, highlighting the need for ongoing maintenance and monitoring to ensure its effectiveness in mitigating flood risks.

Managed by the Nebraska Department of Natural Resources, League Dam is subject to state regulation and inspection, with enforcement measures in place to maintain its structural integrity and safety. The dam's primary purpose is flood risk reduction, aligning with its design as an earth dam with stone core types and soil foundations. Although the dam has not undergone significant modifications in recent years, its last inspection in August 2019 revealed the need for improvement in its overall condition. Water resource and climate enthusiasts can appreciate the vital role League Dam plays in protecting the surrounding area from potential flooding events, while also recognizing the importance of regular maintenance and risk assessment to ensure its continued functionality.

With a limited surface area of 0.01 square miles and a drainage area of 0.2 square miles, League Dam has a maximum discharge capacity of 138 cubic feet per second, highlighting its crucial role in managing water flow during peak flood periods. The dam's location within the Kansas City District of the US Army Corps of Engineers underscores its strategic importance in the region's flood risk management strategy. As climate change continues to impact precipitation patterns and water availability, the maintenance and operation of structures like League Dam will be essential in safeguarding communities and ecosystems from the increasing threat of flooding.
