The Le Sueur Erosion Project, also known as Structure No. 2, is a privately owned flood risk reduction structure located in Le Sueur, Minnesota. Designed by the USDA NRCS and completed in 1968, this earth dam stands at a height of 25 feet and spans 244 feet in length, with a storage capacity of 45 acre-feet. Its primary purpose is flood risk reduction, benefiting the surrounding area by protecting against potential inundation and helping to manage water flow in Lesueur Creek.

Despite its low hazard potential, the Le Sueur Erosion Project plays a crucial role in mitigating erosive forces and safeguarding the local community from flood events. With a moderate risk assessment rating, this structure is monitored for any potential maintenance needs or improvements to ensure its continued effectiveness in protecting the area. As a significant component of the water resource management infrastructure in Le Sueur, this project demonstrates the collaborative efforts between private owners and federal agencies like the Natural Resources Conservation Service to address climate-related challenges and enhance overall water quality and resilience in the region.
