Summary
The earth dam stands at 38 feet high and stretches 292 feet in length, with a storage capacity of 23 acre-feet and a drainage area of 0.08 square miles. Despite its low hazard potential, the dam has not been officially rated for its condition.
The dam, which is privately owned, plays a key role in protecting the surrounding area from potential flooding events. Its strategic location in Jefferson, Iowa, contributes to the overall water resource management in the region, helping to control the flow of water and mitigate risks during heavy rainfall. With its primary purpose being flood risk reduction, Kruger Dam is a significant asset in safeguarding the local community and infrastructure from water-related disasters.
While Kruger Dam has not undergone recent inspections or assessments, its construction and design by the Natural Resources Conservation Service reflect a commitment to enhancing water resource management in the area. As climate change continues to impact weather patterns and water availability, structures like Kruger Dam play a vital role in ensuring the resilience and sustainability of water resources in Iowa. With its modest storage capacity and low hazard potential, Kruger Dam stands as a testament to the importance of proactive flood risk reduction measures in the face of a changing climate.

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.
