Summary
Built in 1964 by the USDA NRCS, this private-owned earth dam stands at a height of 25 feet and spans 618 feet in length. Its primary purpose is flood risk reduction, with a normal storage capacity of 23 acre-feet and a maximum discharge capability of 510 cubic feet per second.
Despite its low hazard potential, Horn Dam 700 is subject to state regulation and inspection by the Nebraska Department of Natural Resources. The dam's condition was last assessed in 2017 and received a "Not Rated" status. While the dam has not been modified in recent years, it remains a critical infrastructure for mitigating flood risks and protecting the surrounding community. The dam's location in a rural area underscores its importance in safeguarding property and lives from potential water-related disasters.
Managed by private owners, Horn Dam 700 plays a vital role in water resource management in the region. With its earth construction and buttress stone core, the dam stands as a testament to effective flood control measures. As climate change continues to impact water resources, structures like Horn Dam 700 will be essential in ensuring the resilience of communities against the threats of flooding and water scarcity.

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.
