Summary

Completed in 2016, this earth dam stands at a height of 25 feet and spans 450 feet in length, providing crucial flood risk reduction for the surrounding area. With a normal storage capacity of 1.5 acre-feet and a drainage area of 0.6 square miles, Adams Park Dam plays a significant role in protecting the community from potential water-related disasters.

Managed by the local government and regulated by the Nebraska Department of Natural Resources, Adams Park Dam has a high hazard potential but is currently assessed as satisfactory in condition. The dam's inspection frequency is yearly, with the most recent assessment conducted in October 2020. With a maximum discharge capacity of 2630 cubic feet per second, the dam is equipped to handle significant water flow during extreme weather events. Additionally, the dam has an Emergency Action Plan in place to ensure swift and effective response in case of emergencies.

Water resource and climate enthusiasts will appreciate the critical role that Adams Park Dam plays in safeguarding the community against floods along the TR-Missouri River. With its strategic design, efficient operation, and regular inspections, the dam stands as a reliable barrier against potential water-related disasters. Its completion in 2016 marks a milestone in flood risk reduction efforts in the region, showcasing the importance of proactive water resource management in climate-vulnerable areas like Omaha, Nebraska.

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.
