Summary
Completed in 1980, this earth dam stands at a height of 31 feet and extends for 466 feet, providing a significant storage capacity of 61 acre-feet. With a primary purpose of flood risk reduction, the dam also serves other essential functions for the local community.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, the Gerdes Smith Grade Stabilization Dam is in satisfactory condition with low hazard potential. Its last inspection in March 2020 confirmed its structural integrity, ensuring the safety of nearby residents and infrastructure. With a drainage area of 0.3 square miles and a maximum discharge capacity of 200 cubic feet per second, this dam plays a crucial role in water resource management in the region.
As an essential piece of infrastructure in the Omaha District, the Gerdes Smith Grade Stabilization Dam not only provides flood protection but also contributes to the overall water security of the area. With its strategic location and effective design, this dam stands as a key asset in safeguarding against the impacts of climate change and ensuring the sustainable management of water resources in Nemaha, Nebraska.

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.
