Summary

Completed in 1976, this earth dam stands at a height of 48 feet, with a structural height of 53 feet, and a hydraulic height of 46 feet. It has a length of 1605 feet and a storage capacity of 3862 acre-feet, serving as a critical resource for water management in the region. The dam is owned by the local government and regulated by the Nebraska Department of Natural Resources, ensuring its proper inspection, enforcement, and permitting processes are in place.

With a drainage area of 9.4 square miles and a maximum discharge capacity of 17,730 cubic feet per second, Maskenthine Dam plays a crucial role in safeguarding the surrounding communities from potential flooding events. Despite its high hazard potential, the dam is currently assessed to be in fair condition, with regular inspections conducted to ensure its safety and functionality. The emergency action plan for the dam, last revised in February 2018, serves as a guideline for risk management and emergency response, highlighting the importance of preparedness and proactive measures in mitigating any potential threats.

As part of the flood risk reduction strategy, Maskenthine Dam serves as a key infrastructure project in the region, providing essential protection for the local area against potential water-related disasters. With its strategic location on Maskenthine Creek and close oversight by regulatory agencies, including the Nebraska DNR, the dam stands as a testament to effective water resource management and climate resilience efforts in Nebraska.

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.
