Summary

Built in 1950, this private dam on TR-Big Cottonwood Creek serves multiple purposes, including flood risk reduction and other vital functions. With a height of 18.3 meters and a storage capacity of 89.1 acre-feet, this earth dam plays a crucial role in protecting the surrounding area from potential hazards.

Managed by the Nebraska Department of Natural Resources, James Dam 8982 has a low hazard potential and a condition assessment that is currently not rated. Despite its age, the dam remains structurally sound and has a regular inspection frequency of 5 years. With a drainage area of 0.8 square kilometers and a surface area of 9.7 hectares, this dam is a key component of the local water infrastructure, ensuring the safety and well-being of the community.

As an integral part of the Omaha District's water management system, James Dam 8982 continues to provide essential services to the region. With its strategic location and effective design, this dam exemplifies the importance of proactive measures in safeguarding water resources and mitigating the impacts of a changing climate. For water resource and climate enthusiasts, James Dam 8982 is a fascinating case study in sustainable infrastructure development and resilience planning.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
