Summary
As a privately owned structure, it stands at a height of 13.9 feet and has a storage capacity of 63.9 acre-feet, with a normal storage of 18.9 acre-feet. The dam's condition assessment in 2015 rated it as poor, with a hazard potential of low.
Despite its age, Cline Dam 8683 remains under the regulatory oversight of the Nebraska Department of Natural Resources, with state permitting, inspection, and enforcement all in place. The dam's design, made of earth and stone, rests on a soil foundation and spans a length of 360 feet, covering a surface area of 4.7 acres. While the dam has not undergone any major modifications in recent years, its last inspection in 2015 highlighted the need for improvements to bring it up to satisfactory standards.
Given its critical role in flood risk reduction in the region, Cline Dam 8683 serves as a vital infrastructure for water resource management in Nebraska. With ongoing monitoring and potential upgrades, the dam's resilience and effectiveness in safeguarding the surrounding area from flooding can be further enhanced to meet the demands of changing climate conditions and evolving safety standards.

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.
