Summary
Completed in 2003, this earth dam stands at a height of 20 feet and spans a length of 620 feet, providing a storage capacity of 67 acre-feet. With a primary purpose of grade stabilization, this dam plays a significant role in managing water resources in the region.
Managed and regulated by the Iowa Department of Natural Resources, the Wayne CO Road Dam 32-70-20 has a low hazard potential and a moderate risk assessment rating. Despite not being currently rated for condition assessment, the dam serves as a vital infrastructure in protecting the surrounding area from potential flooding events. With its uncontrolled spillway and soil foundation, this dam is a key component of the water management system in the Rathbun Reservoir area, ensuring the safety and stability of the local community.
While lacking certain operational details and inspection frequency data, the Wayne CO Road Dam 32-70-20 remains a critical structure in the region, contributing to the overall water resource management efforts. As climate change continues to impact water availability and quality, structures like this play a crucial role in safeguarding communities and ecosystems from the adverse effects of extreme weather events. Enthusiasts and stakeholders in water resources and climate resilience can appreciate the importance of this dam in maintaining the ecological balance and sustainable development in Wayne County, Iowa.

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.
