Summary
Managed by the local government, this dam on the TR-Mule Creek is regulated by the Iowa Department of Natural Resources and is designed by the USDA SCS. With a height of 43 feet and a storage capacity of 127 acre-feet, the dam serves to reduce flood risks in the area and covers a surface area of 5.2 acres.
With a low hazard potential and a moderate risk assessment score of 3, the Mule Creek Watershed Sta 78+37 is currently not rated for its condition assessment. Despite its importance for water resource management, the dam does not have any associated structures and has not been inspected recently. While it meets state regulations for permitting, inspection, and enforcement, the dam lacks an emergency action plan and updated contact information, raising concerns for its risk management and emergency preparedness.
Overall, the Mule Creek Watershed Sta 78+37 plays a crucial role in the local water resource management system, providing essential services for fire protection, stock, and flood risk reduction. As water resource and climate enthusiasts continue to monitor and assess the condition of this earth dam, there is a need for enhanced risk management measures, regular inspections, and updated emergency action plans to ensure the safety and sustainability of this important infrastructure in the Mule Creek watershed.

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.
