Summary
The dam's primary purpose is flood risk reduction, serving as a critical infrastructure along the TR-LOUP River. Standing at a height of 22 feet and stretching 220 feet in length, this dam has a storage capacity of 57 acre-feet and a drainage area of 0.5 square miles.
Managed and regulated by the Nebraska Department of Natural Resources, Horn Dam 215 has a low hazard potential and is deemed to be in satisfactory condition as of the last inspection in April 2020. The dam's hydraulic height reaches 19 feet, with a maximum discharge capacity of 165 cubic feet per second. While the dam does not have a spillway, it plays a vital role in protecting the surrounding area from flooding events.
Water resource and climate enthusiasts can appreciate Horn Dam 215 for its contribution to flood risk reduction in the region. With its efficient design and satisfactory condition, this earth dam stands as a testament to the importance of responsible water management and infrastructure maintenance. As part of the broader network of dams in Nebraska, Horn Dam 215 plays a crucial role in safeguarding communities and natural resources along the TR-LOUP River.

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.
