Walden Dam, located in Nelson, Nebraska, is a privately owned structure designed by the USDA NRCS and regulated by the Nebraska Department of Natural Resources. Completed in 1939, this earth dam stands at a height of 28 feet and spans 735 feet in length, with a primary purpose of flood risk reduction for the TR-ELK CREEK river. The dam has a storage capacity of 321 acre-feet and a maximum discharge rate of 944 cubic feet per second, making it a crucial asset for managing water resources in the area.

Despite its age, Walden Dam is in fair condition with a low hazard potential, as assessed during its last inspection in March 2020. The dam sits on a foundation of soil with a core made of buttress and stone, contributing to its structural stability. While the dam does not have a spillway or outlet gates, it serves as a key component in mitigating flood risks and protecting the surrounding Nuckolls County community. With its continued state inspections and enforcement measures, Walden Dam remains a vital asset in safeguarding against potential water-related emergencies and ensuring water resource sustainability in the region.

For water resource and climate enthusiasts, Walden Dam presents an intriguing case study of a historic structure designed for flood risk reduction in rural Nebraska. As a privately owned and state-regulated entity, the dam showcases the collaboration between various agencies to manage water resources effectively. With its modest height and capacity, Walden Dam exemplifies the importance of maintaining aging infrastructure to ensure the resilience of communities against natural disasters. As climate change continues to impact water systems, the role of dams like Walden in safeguarding against floods and managing water flow becomes increasingly significant for sustainable water resource management in the future.
