Summary
With a height of 29 feet and a length of 660 feet, this dam serves multiple purposes, including flood risk reduction and other water resource management activities. It has a storage capacity of 257 acre-feet and covers a surface area of 8 acres, with a drainage area of 1.7 square miles.
Managed by the Nebraska Department of Natural Resources, Elson Detention Dam 1-N is subject to state regulations, inspections, and enforcement to ensure its safety and functionality. Despite being categorized as having a significant hazard potential, the dam's condition assessment in 2019 deemed it to be satisfactory, with regular inspections scheduled every three years. The dam's location on Curtis Creek, a tributary of the Republican River, highlights its importance in managing water resources and mitigating flood risks in the region.
As part of the Omaha District, Elson Detention Dam 1-N plays a crucial role in water resource management in Frontier County, Nebraska. With its design by the Natural Resources Conservation Service and its significant storage capacity, this dam contributes to the overall water infrastructure of the area. Its presence underscores the importance of proper dam maintenance and regulation in ensuring a sustainable water supply and effective flood control measures for the community.

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.
