Summary

Completed in 2014, this earth dam stands at a height of 33 feet and has a maximum storage capacity of 69.4 acre-feet. With a normal storage capacity of 11.8 acre-feet and a surface area of 2.09 acres, Coatney Dam plays a crucial role in managing water resources in the area.

Managed by the local government and regulated by the NE DNR, Coatney Dam is in satisfactory condition with a low hazard potential. The dam has a drainage area of 0.49 square miles and a maximum discharge capacity of 163 cubic feet per second. Despite its low hazard potential, regular inspections are conducted, with the last assessment taking place in April 2018. Additionally, the dam has an inspection frequency of 5 years to ensure its structural integrity and safety.

Coatney Dam provides essential water resource management for the area, ensuring adequate water supply for fire protection, livestock, and recreational activities such as fishing. With its strategic location on the TR-Buck Creek and close proximity to Congressional District 03 represented by Adrian Smith, Coatney Dam stands as a key infrastructure supporting local water needs while maintaining a low-risk profile for the community.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
