Summary
Built in 1971, this earth dam stands at a height of 18.6 feet and spans 700 feet in length. With a storage capacity of 414.5 acre-feet and a drainage area of 2.76 square miles, it plays a crucial role in managing water resources in the region.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Dawson County Road Dam 7 is inspected every five years to ensure its structural integrity and safety. Despite its low hazard potential, the dam's condition assessment remains unrated as of the last inspection in 2017. The dam's primary purpose extends beyond flood risk reduction to include other water resource management objectives, making it a key component in the region's overall water infrastructure.
In the event of an emergency, the dam's preparedness and risk management measures are not currently outlined in an Emergency Action Plan (EAP). However, with its strategic location and importance in water resource management, Dawson County Road Dam 7 continues to be a critical asset for climate and water resource enthusiasts in the area.

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.
