Summary
Built in 1960, this earth dam stands at a height of 14.4 feet and has a length of 335 feet, providing a storage capacity of 50.9 acre-feet. Despite its low hazard potential, the dam's condition is assessed as poor, with the last inspection conducted in April 2017.
Managed by the Nebraska Department of Natural Resources, Maska Dam is subject to state regulations and inspections to ensure its safety and effectiveness in flood control. The dam's primary purpose is flood risk reduction, serving the local community by preventing potential inundation during periods of heavy rainfall or snowmelt. While the dam's condition may be concerning, ongoing monitoring and maintenance efforts are crucial to mitigate any risks and ensure the dam's continued functionality in protecting the surrounding area from flooding events.
With its strategic location and vital role in flood risk management, Maska Dam serves as a critical infrastructure asset in the region. As climate change continues to amplify the frequency and intensity of extreme weather events, the importance of well-maintained structures like Maska Dam cannot be overstated. By staying vigilant in monitoring its condition and implementing necessary repairs and upgrades, stakeholders can ensure the long-term resilience and effectiveness of this essential water resource management facility.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
