Summary
With a height of 24 feet and a length of 496 feet, this dam serves multiple purposes including fire protection and stock or small fish pond management. It has a storage capacity of 80 acre-feet and covers a surface area of 7 acres.
The dam is regulated by the Iowa Department of Natural Resources and has a low hazard potential, with a moderate risk assessment rating. Despite not being rated for its condition, the dam is inspected, permitted, and enforced regularly by the state agencies. Although it does not have an Emergency Action Plan (EAP) in place, the dam's risk management measures are deemed to be adequate.
Situated on the TR-Middle Raccoon River, Garst Warehouse CO Dam plays a crucial role in water resource management in the area. While it may not have a significant impact on the surrounding environment, its presence ensures the safety and stability of the water supply and ecosystem. For water resource and climate enthusiasts, this dam serves as a testament to the importance of maintaining and regulating man-made structures to support sustainable water management practices.

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.
