Easton 6439 Dam is a privately owned structure located in Thayer, Nebraska, with a primary purpose of serving as a fire protection, stock, or small fish pond. Completed in 1980, this earth dam stands at a height of 21.9 feet and has a storage capacity of 111.9 acre-feet. Situated on the TR-DRY CREEK, the dam plays a crucial role in managing water resources in the area, with a drainage area of 0.42 square miles and a surface area of 5.7 acres.

Despite its low hazard potential, the dam's condition assessment is classified as poor, highlighting the need for maintenance and improvements to ensure its structural integrity and safety. The last inspection conducted in April 2019 indicated the need for attention, with an inspection frequency of 10 years. While the dam has state regulatory oversight from the Nebraska Department of Natural Resources, it lacks certain emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps, raising concerns about its resilience to potential risks and natural disasters.

For water resource and climate enthusiasts, Easton 6439 Dam presents an intriguing case study of a privately owned earth dam in rural Nebraska. With its unique primary purpose and historical significance, the dam serves as a vital element in the local ecosystem and water management infrastructure. However, the dam's current poor condition assessment and lack of certain emergency preparedness measures underscore the importance of ongoing monitoring, maintenance, and risk management to ensure its longevity and functionality in the face of changing climate conditions and potential hazards.
