Summary
Completed in 1980, this earth dam stands at a height of 14.1 feet and spans 700 feet along TR-DEER CREEK CANYON. With a storage capacity of 157.3 acre-feet and a surface area of 3.8 acres, this dam plays a crucial role in protecting the surrounding community from potential flooding events.
Managed by the Nebraska Department of Natural Resources, the Road 731 County Dam is subject to regular inspections to ensure its structural integrity and safety. Despite being rated as having a low hazard potential, its condition remains unrated as of the last assessment in June 2018. The dam's emergency action plan and risk assessment measures are currently not available, highlighting the need for continued monitoring and maintenance to uphold its flood risk reduction purpose effectively.
With its primary focus on flood risk reduction, the Road 731 County Dam serves as a key asset in safeguarding the local area from potential water-related disasters. As part of the Omaha District under the US Army Corps of Engineers, this dam underscores the importance of sustainable water resource management and climate resilience efforts in protecting communities and infrastructure from the impacts of extreme weather events.

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.
