Summary
Built in 1980, this private-owned earth dam stands at a height of 38.4 feet and has a storage capacity of 1353 acre-feet, with a normal storage level of 111.2 acre-feet. Despite its low hazard potential, the dam's condition assessment is currently rated as poor, indicating the need for maintenance and potential upgrades to ensure its long-term effectiveness.
Managed by the Nebraska Department of Natural Resources, Nelsen Dam 4068 is subject to state regulations and inspections to guarantee its structural integrity and safety. While the dam's primary purpose is flood risk reduction, its associated structures and spillway details are not specified in the available data. The dam's location within Congressional District 03, Nebraska, underlines its significance in protecting the local community and surrounding areas from potential water-related disasters.
As water resource and climate enthusiasts, the data on Nelsen Dam 4068 offers valuable insight into the infrastructure's role in managing water flow and mitigating flood risks in Frontier County, Nebraska. With its strategic placement and operational history, the dam stands as a testament to the ongoing efforts to safeguard communities and enhance water resource management in the region. Efforts to address its current poor condition and ensure compliance with state regulations are essential steps towards maintaining the dam's effectiveness and resilience in the face of changing climate patterns.

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.
