Summary

Completed in 2001, this earth dam stands at a height of 8 feet with a length of 6650 feet, providing a storage capacity of 436 acre-feet. The dam also serves as a habitat for various wildlife species in the area, contributing to the conservation efforts of the region.

Managed by the Iowa DNR, Mullahy Wetland Dam is considered to have low hazard potential and a moderate risk assessment. Despite not being rated for its condition, the dam is regularly inspected and maintained by state authorities. The surrounding area encompasses a surface area of 116.9 acres with a drainage area of 0.8 square miles, ensuring the efficient management of water resources in the region.

For water resource and climate enthusiasts, Mullahy Wetland Dam presents a unique opportunity to witness the intersection of environmental conservation and infrastructure development. With its focus on creating a sustainable habitat for fish and wildlife, this dam serves as a model for balancing the needs of nature with those of human communities. As efforts continue to enhance the resilience of the dam and surrounding ecosystem, Mullahy Wetland Dam stands as a testament to the importance of responsible water resource management in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
