Summary
Constructed in 1975, this earth dam stands at 26 feet in height and spans 1083 feet in length, providing essential flood protection for the surrounding area. With a capacity to store 329 acre-feet of water, this dam plays a crucial role in managing water resources in the region.
Despite its importance, Moody Group Dam's condition assessment reveals a poor rating, highlighting the need for maintenance and upkeep. The dam's hazard potential is considered low, but regular inspections every 5 years are required to ensure its structural integrity. Operated by the local government, the dam serves as a key asset in flood risk reduction efforts, demonstrating the collaborative efforts between state and federal agencies in safeguarding communities against potential disasters.
With the Nebraska DNR overseeing state regulation and enforcement, Moody Group Dam remains a cornerstone in water resource management and climate resilience in Brown County. As climate change continues to impact the frequency and intensity of extreme weather events, the importance of maintaining and upgrading critical infrastructure like Moody Group Dam becomes increasingly apparent. As such, ongoing monitoring and maintenance efforts are essential to ensure the dam's effectiveness in safeguarding the community and surrounding areas from the risks of flooding.

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.
