Summary
The earth-type dam stands at a height of 27 feet and spans a length of 550 feet, providing a storage capacity of 49 acre-feet. Situated on the TR-Boyer River, the dam has a low hazard potential and is regulated by the Iowa Department of Natural Resources.
Despite its modest size, Dozark Dam plays a crucial role in managing water resources in the area, with a normal storage capacity of 19 acre-feet and a surface area of 3.2 acres. While its spillway is uncontrolled, the dam's risk assessment indicates a moderate level of risk, emphasizing the importance of regular inspections and maintenance to ensure its structural integrity. The surrounding community of Arion benefits from the dam's presence, highlighting the interconnectedness of water resource management and climate resilience in the region.
Managed by the local government, Dozark Dam serves as a vital infrastructure for the community, supporting both practical and recreational purposes. With the support of the Natural Resources Conservation Service, the dam continues to play a key role in water management efforts, underscoring the importance of sustainable practices in safeguarding our water resources for future generations. For water resource and climate enthusiasts, Dozark Dam represents a fascinating example of the intersection between infrastructure development, environmental stewardship, and community resilience in the face of changing climate conditions.

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.
