Summary
The dam, primarily owned by a private entity, is regulated by the Iowa Department of Natural Resources and is subjected to regular inspections and enforcement. The earth dam stands at a height of 28 feet with a length of 325 feet, providing a storage capacity of 23 acre-feet.
With a low hazard potential and a moderate risk assessment, Mc Coy Dam has not been rated for its condition assessment. Despite its small surface area of 2 acres, the dam plays a crucial role in water resource management in the region, specifically for fire protection and agricultural uses. Situated on the TR- North Avery Creek, the dam contributes to the conservation efforts in the area and highlights the importance of sustainable water resource management in the face of changing climate patterns.
As an integral part of the water infrastructure in Monroe County, Iowa, Mc Coy Dam showcases the collaboration between private owners, federal agencies, and state regulators in ensuring the safety and functionality of the structure. With its low hazard potential and moderate risk assessment, the dam serves as a vital resource for the local community and underscores the significance of maintaining and monitoring water resources in the region. Climate enthusiasts and water resource advocates can appreciate the role of Mc Coy Dam in supporting the ecosystem and ensuring water security for various purposes in the area.

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.
