Walker is a hydroelectric dam located in Cozad, Nebraska, with a primary purpose of generating electricity and providing irrigation water. Completed in 1941, this earth dam stands at a height of 43 feet and spans 550 feet in length, with a storage capacity of 600 acre-feet. The dam is owned and regulated by the Nebraska Department of Natural Resources, with inspections conducted by the Federal Energy Regulatory Commission.

Despite its low hazard potential, Walker poses a high risk due to the surrounding area's susceptibility to climate-related events. With a limited emergency action plan and no recent condition assessment available, there are concerns about the dam's ability to withstand potential challenges. However, the dam's historical significance as a hydroelectric and irrigation structure underscores its importance in the region's water resource management and climate resilience efforts. As water resource and climate enthusiasts, monitoring and improving the safety and functionality of Walker is crucial for sustainable water management in the area.
