Summary
With a height of 27 feet and a length of 513 feet, this dam serves to control water flow in the TR-Cub Creek, with a maximum discharge capacity of 376 cubic feet per second. The dam has a low hazard potential and is in satisfactory condition, as per the last inspection conducted in May 2019.
Managed by the Nebraska Department of Natural Resources, Cub Creek G-1 has a normal storage capacity of 17 acre-feet and a drainage area of 0.5 square miles. The dam's primary purpose is classified as "Other," alongside flood risk reduction, with a core made of stone and a foundation in soil. Despite its low hazard potential, the dam is regularly inspected every five years to ensure its structural integrity and functionality. With its strategic location and design, Cub Creek G-1 plays a crucial role in water resource management and climate resilience efforts in the region.
Overall, Cub Creek G-1 stands as a vital infrastructure asset in Gage County, providing essential flood control measures and water management capabilities for the local community. With state-regulated permitting, inspection, and enforcement protocols in place, this earth dam serves as a testament to effective collaboration between federal agencies, local governments, and environmental conservation efforts in Nebraska. As water resource and climate enthusiasts continue to prioritize sustainable infrastructure development, Cub Creek G-1 sets a precedent for effective dam management and risk mitigation strategies in the face of changing environmental conditions.

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.
