Summary
Managed by the USDA NRCS, this Earth dam stands at 24 feet high and stretches 698 feet in length, with a storage capacity of 79 acre-feet. Completed in 1997, this site plays a crucial role in flood risk reduction within the region, serving as a low-hazard structure with a moderate risk assessment rating.
Operated by the Iowa DNR, Soap Creek Watershed Site 68-47 is regulated, permitted, and inspected by state authorities to ensure its structural integrity and compliance with environmental standards. The dam, built on soil foundations, is located along the TR-Soap Creek and covers a drainage area of 0.25 square miles. With a surface area of 5 acres and a normal storage capacity of 19 acre-feet, this site plays a significant role in water resource management in the region. Despite being uncontrolled, the spillway type at this site ensures the safe release of excess water during heavy rainfall events.
The Soap Creek Watershed Site 68-47 serves as a crucial infrastructure for water resource and climate enthusiasts in the area. With its strategic location, purposeful design, and state regulation, this dam plays a key role in safeguarding the local community from flood risks and ensuring sustainable water management practices for the future. Its low-hazard potential, along with moderate risk assessment, highlights its importance in maintaining the ecological balance and water security 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.
