Summary

Completed in 1996, this earth-type dam stands at a height of 30 feet, with a structural height of 33 feet and a length of 767 feet. It has a normal storage capacity of 63 acre-feet and a maximum storage capacity of 435 acre-feet, covering a surface area of 13 acres and draining a 0.9 square mile area.

Managed by the local government and regulated by the Nebraska Department of Natural Resources, Magee Dam has been assessed as having low hazard potential and is considered to be in satisfactory condition. The dam is regularly inspected, with the last assessment conducted in October 2016. Situated in a rural area near Lincoln, the dam plays a crucial role in protecting the surrounding community from potential flooding events, with a maximum discharge capacity of 4,970 cubic feet per second.

With its strategic location and efficient design, Magee Dam stands as a testament to effective water resource management and climate resilience efforts in Nebraska. As a key infrastructure for flood risk reduction, this dam exemplifies the importance of proactive measures to safeguard communities and ecosystems from the impacts of extreme weather events. Its continued maintenance and inspection ensure the safety and well-being of the area, serving as a crucial component in the region's water resource and climate adaptation strategies.

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.
