Summary
This earth dam, completed in 1953, has a height of 25 feet and a storage capacity of 55 acre-feet, serving a drainage area of 0.39 square miles along the TR- Mule Creek stream. Despite having a low hazard potential, the dam's risk assessment is rated as moderate, indicating the need for careful monitoring and maintenance.
Operated and regulated by the Iowa Department of Natural Resources, Mule Creek Watershed Site 1 plays a crucial role in flood risk reduction within the region. The dam's condition assessment is currently not rated, highlighting the importance of regular inspections to ensure its structural integrity and functionality. Additionally, the dam lacks an Emergency Action Plan (EAP) and inundation maps, suggesting a need for further risk management measures to enhance preparedness and response capabilities in case of emergencies.
Overall, Mule Creek Watershed Site 1 stands as a valuable asset in water resource management, contributing to the conservation efforts in the region. With its strategic location in the Omaha District and a primary purpose of safeguarding against fire hazards and supporting local livestock, this earth dam serves as a critical infrastructure for sustainable water usage and environmental protection 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.
