Summary
Managed by the USDA NRCS, this local government-owned site serves multiple purposes including fire protection, stock, and small fish pond maintenance, as well as flood risk reduction. The earth dam, completed in 1998, stands at a height of 27 feet and spans a length of 510 feet, providing a storage capacity of 125 acre-feet.
With a low hazard potential and a moderate risk assessment rating, Soap Creek Watershed Site 4-56 plays a crucial role in managing water resources in the area. Governed by the Iowa DNR and meeting state regulatory standards for inspection and enforcement, this site ensures the safety and sustainability of the surrounding environment. The presence of an uncontrolled spillway and soil foundation further enhances its functionality, with a drainage area of 0.41 square miles and a surface area of 5.8 acres contributing to its overall efficiency.
As part of the overall water management strategy in the region, Soap Creek Watershed Site 4-56 stands as a testament to the collaborative efforts between local government agencies and the USDA NRCS. Its strategic location along TR-Soap Creek and its contribution to flood risk reduction highlight its importance in maintaining ecological balance and supporting the community's water needs. With a focus on conservation and sustainability, this site serves as a model for effective water resource management in the region.

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.
