Summary
Completed in 1963, this earth dam stands at a height of 32 feet and has a structural height of 36 feet, with a storage capacity of 53 acre-feet. With a low hazard potential and satisfactory condition assessment, Horn Dam 4 plays a vital role in protecting the surrounding community from potential flooding events.
Managed and regulated by the Nebraska Department of Natural Resources, Horn Dam 4 is subject to state permitting, inspection, and enforcement to ensure its safety and effectiveness in flood risk reduction. The dam is situated along the Logan Canyon, providing essential drainage and water management for a drainage area of 1.1 square miles. Despite its modest size, this dam serves as a critical infrastructure for water resource management in the region, highlighting the importance of private-public partnerships in addressing climate-related challenges.
With a maximum discharge capacity of 270 cubic feet per second, Horn Dam 4 is equipped to handle significant water flow during heavy rainfall or flood events. The dam's location, design, and maintenance reflect a commitment to sustainability and resilience in the face of changing climate patterns. As climate enthusiasts and water resource advocates, understanding the role of structures like Horn Dam 4 is essential in mitigating the impacts of climate change on our water systems and communities.

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.
