Summary
The dam, designed by USDA NRCS, serves multiple purposes including fire protection, stock maintenance, and small fish pond creation. Completed in 1965, the earth dam stands at a height of 40 feet and spans 545 feet in length, with a storage capacity of 59 acre-feet and a drainage area of 1.25 square miles.
The dam on Mucky Creek Subwatershed is regulated by the Iowa Department of Natural Resources and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating. The primary purpose of the dam is flood risk reduction, ensuring the safety and protection of the surrounding Maple River area. Despite not being rated for condition assessment, the dam continues to play a crucial role in water management and conservation efforts in the region.
With its strategic location and importance in mitigating flood risks, the Mucky Creek Subwatershed Sta 57+00 is a key asset for water resource and climate enthusiasts. Managed by the local government and designed by USDA NRCS, this earth dam stands as a testament to sustainable water management practices. As efforts continue to monitor and regulate the dam, it remains a critical infrastructure for maintaining the ecological balance and safeguarding the community from potential water-related hazards.

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.
