Summary
Roadgrade Dam 21-67-22, located in Wayne County, Iowa, is a local government-owned earth dam completed in 1996 with a primary purpose of recreation. The dam, standing at a height of 42 feet and stretching 1400 feet in length, holds a normal storage capacity of 560 acre-feet and a maximum storage capacity of 7900 acre-feet. Situated on the TR- W.FK. MEDICINE CREEK, this dam plays a crucial role in water resource management in the area.
Despite its low hazard potential, the dam's condition assessment in December 2020 deemed it unsatisfactory, highlighting the need for maintenance and improvements to ensure its structural integrity and safety. The dam is regulated by the Iowa Department of Natural Resources (DNR) and undergoes regular inspections with a frequency of 5 years. The risk assessment for the dam is moderate, indicating the importance of implementing risk management measures to mitigate potential hazards and safeguard the surrounding communities and environment.
As a significant structure in the region, Wayne Co. Roadgrade Dam 21-67-22 not only provides recreational opportunities but also serves as a vital component of the local water resource infrastructure. With its close monitoring and regulation by the Iowa DNR, efforts are being made to address the unsatisfactory condition and manage the moderate risk associated with the dam. Continued maintenance and risk management measures will be essential in ensuring the long-term safety and effectiveness of this important water resource asset.

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.
