Summary
This earth dam stands at a height of 22 feet and has a length of 512 feet, providing a storage capacity of 78 acre-feet. Situated on TR- Mitchells Run, the dam has a low hazard potential and is currently rated as not assessed. Despite its low hazard potential, the dam is regulated and inspected by the Iowa Department of Natural Resources.
The dam's primary purpose is to provide fire protection and support various recreational activities such as fishing. Greenberg Dam's location in a rural area makes it an essential resource for the surrounding community and wildlife. Although the dam has not been rated for its condition, it is vital for maintaining water resources in the area and enhancing the local ecosystem. With a moderate risk assessment rating, there may be potential management measures in place to ensure the dam's safety and functionality.
Overall, Greenberg Dam plays a crucial role in water resource management and climate resilience in the Ringgold County area. As a privately owned structure, the dam provides essential services for both human and ecological needs. With its low hazard potential and moderate risk assessment, ongoing monitoring and management practices may be necessary to ensure the dam's continued safety and effectiveness in supporting the local community and environment.

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.
