Summary

Constructed in 1980, this private-owned earth dam stands at a height of 25 feet and has a hydraulic height of 23 feet. With a storage capacity of 116 acre-feet, the dam primarily caters to agricultural irrigation needs in the area. The dam spans a length of 445 feet and has a surface area of 8 acres, providing essential water resources for the surrounding lands.

Managed and regulated by the Nebraska Department of Natural Resources, the David Mazour Dam is inspected regularly to ensure its structural integrity and functionality. The dam's condition is assessed as fair, with the last inspection conducted in March 2020. The dam plays a crucial role in water management, especially during periods of drought or low precipitation, highlighting its significance in sustaining agricultural activities and water supply in the region. With its strategic location on TR-Liberty Creek, the dam is a key component of the local water infrastructure.

As a part of the Omaha District, this dam is a testament to the collaborative efforts between private entities and government agencies in managing water resources effectively. With a focus on irrigation purposes, the David Mazour Dam stands as a symbol of sustainable water resource management in Nebraska, showcasing the importance of infrastructure projects in supporting agriculture and mitigating the impacts of climate change on water availability.

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.
