Summary

Completed in 1992, this earth dam stands at a height of 121 feet and has a maximum storage capacity of 9,500 acre-feet. The dam spans a length of 1,600 feet and has a surface area of 157 acres, providing crucial water management infrastructure for the region.

Despite its important role in water resource management, Maggie Creek Dam has been assessed as being in poor condition with a high hazard potential. The dam's last inspection in October 2021 highlighted the need for structural improvements. With a risk assessment rating of moderate (3), the dam's management measures and risk mitigation strategies are crucial for ensuring the safety and functionality of the structure.

As a privately owned dam regulated by the Nevada Department of Water Resources, Maggie Creek Dam plays a significant role in managing flood risks and providing water for various uses in the region. With ongoing monitoring and maintenance efforts, the dam continues to serve as a vital water resource infrastructure for the community, highlighting the importance of sustainable management practices in the face of changing climate conditions.

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.
