Rath Dam Reservoir Report
Last Updated: March 16, 2026
Rath Dam, located in Avion, Iowa, was completed in 2004 and serves multiple purposes including fire protection, stock, and small fish pond.
Summary
This private dam, designed by NRCS, stands at a height of 32 feet with a length of 352 feet. It has a storage capacity of 41 acre-feet and covers a surface area of 2.8 acres in Crawford County.
Managed by the Iowa DNR, Rath Dam is state-regulated and undergoes regular inspections and enforcement to ensure its safety and compliance with regulations. With a low hazard potential and a moderate risk assessment rating of 3, the dam plays a crucial role in water resource management and flood control along the TR- Coon Creek.
Enthusiasts of water resources and climate will find Rath Dam to be a fascinating structure that not only provides essential services like fire protection and water storage but also contributes to the ecosystem by creating a habitat for small fish. Its strategic location and design make it a vital asset in the region's water management infrastructure, ensuring the safety of nearby communities and enhancing the overall environmental resilience in Crawford County, Iowa.

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.
