Summary
This dam stands at a height of 30 feet and spans 325 feet in length, providing a storage capacity of 51 acre-feet. Situated along the TR-Middle Raccoon River, this dam serves as a vital resource for water management in the region, with a low hazard potential and a moderate risk assessment rating.
Managed by the Iowa Department of Natural Resources, Garst Warehouse CO Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. With a drainage area of 0.35 square miles and a surface area of 3 acres, this dam plays a crucial role in controlling water flow and providing essential water resources for the surrounding area. Despite its condition not being rated, the dam's risk assessment remains moderate, highlighting the importance of ongoing monitoring and management measures to mitigate potential risks and ensure its long-term resilience in the face of changing climatic conditions.
In the event of an emergency, the dam's Emergency Action Plan (EAP) status is not currently available, indicating a need for further preparedness and coordination. However, with its primary purpose of water storage and fire protection, Garst Warehouse CO Dam stands as a key infrastructure for both agricultural and recreational activities in the region, showcasing the intersection of water resource management and climate resilience in addressing the challenges of a changing 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.
