Summary
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.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
