Summary

This local government-owned earth dam, completed in 1995, boasts a height of 31 feet and a length of 1280 feet, providing a storage capacity of 799 acre-feet. The dam's stone core and soil foundation support its structure, as it serves to protect the surrounding area from potential hazards with its low hazard potential and fair condition assessment.

Managed by the Nebraska Department of Natural Resources, the Maskenthine Sediment Dam is regulated, inspected, and enforced by state agencies to ensure its continued functionality and safety. The dam's design and construction align with state permitting and jurisdiction requirements, underscoring its importance in maintaining water resources and mitigating climate impacts in the region. With a drainage area of 7.8 square miles and a maximum discharge capacity of 648 cubic feet per second, the dam plays a crucial role in water management and environmental conservation efforts in the area.

Under the jurisdiction of the Omaha District of the US Army Corps of Engineers, the Maskenthine Sediment Dam exemplifies collaboration between local and federal entities in safeguarding communities from water-related risks. With its strategic location, sound engineering, and consistent inspections, the dam continues to be a cornerstone in water resource management, showcasing the importance of proactive measures in addressing climate challenges and preserving natural ecosystems.

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.
