Summary
Completed in 1973, this earth dam stands at a height of 32 feet with a length of 444 feet, providing a storage capacity of 60 acre-feet and covering a surface area of 3.9 acres. It serves the local community by reducing flood risks and safeguarding the surrounding area from potential hazards.
Managed by local government authorities and regulated by the Iowa Department of Natural Resources, this dam is crucial for water resource management and climate resilience in the region. With a low hazard potential and moderate risk assessment, this structure plays a key role in maintaining water quality and supporting ecological biodiversity in the Mud Creek watershed. Although its condition assessment is currently not rated, regular inspections and enforcement measures ensure the safety and functionality of this essential infrastructure for the community.
While not owned or funded by federal agencies, Mud Creek Subwatershed Site 6-1 exemplifies local efforts in water resource management and emergency preparedness. As a part of the Omaha District, this structure aligns with state permitting and inspection requirements, highlighting the collaborative approach towards sustainable water infrastructure development in the area. With its strategic location and purposeful design, this dam stands as a testament to the community's commitment to preserving water resources and adapting to changing climate conditions for a more resilient future.

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.
