Wilson Creek 3-1a, located in Otoe, Nebraska, is a significant earth dam designed by the USDA NRCS in 1976 for flood risk reduction along the TR-N FK Little Nemaha River. This structure spans 324 feet in length and stands at a height of 32 feet, with a storage capacity of 62 acre-feet. Despite its low hazard potential, the dam's current condition is assessed as poor according to a 2019 inspection, indicating a need for maintenance and potential upgrades to ensure its long-term functionality.

Managed by the local government with regulatory oversight from the Nebraska Department of Natural Resources, Wilson Creek 3-1a plays a crucial role in water resource management within the region. The dam's primary purpose extends beyond flood risk reduction to include various other uses, highlighting its importance in maintaining water quality, regulating flow, and supporting ecological balance. Additionally, its proximity to Talmage underscores the critical role it plays in protecting local communities from potential flooding events.

As a key infrastructure asset in the area, Wilson Creek 3-1a is subject to regular inspections and enforcement measures to ensure its structural integrity and operational efficiency. The dam's design, construction, and regulatory oversight are all carried out by the Natural Resources Conservation Service, emphasizing the collaborative effort between federal and state agencies in managing water resources and mitigating climate-related risks in Nebraska. Moving forward, continued monitoring and maintenance of Wilson Creek 3-1a will be essential to safeguarding its function and enhancing overall water resource management in the region.
