Summary
Constructed in 1997 by the USDA NRCS, this earth dam stands at 24 feet tall and spans 937 feet, with a storage capacity of 131 acre-feet. Despite its low hazard potential, this dam serves as a flood risk reduction measure for the surrounding area, with a drainage area of 0.47 square miles and a surface area of 6.5 acres.
Managed by the Iowa DNR, this site is state-regulated and inspected for compliance with safety standards. The dam features an uncontrolled spillway and a soil foundation, ensuring its structural integrity and functionality. While its condition is currently not rated, the risk assessment indicates a moderate level of risk, prompting the need for ongoing risk management measures. With a designated emergency action plan and updated contact information, Soap Creek Watershed Site 26-34 remains a crucial component of the local water resource infrastructure in Davis County, Iowa.
As part of the Rock Island District, this site plays a vital role in water management and conservation efforts in the region. Supported by federal funding and design from the Natural Resources Conservation Service, this dam provides essential water storage and flood control functions while also enhancing wildlife habitat and recreational opportunities in the area. With its strategic location along TR-SOAP CREEK, this watershed site serves as a model for sustainable water resource management and climate resilience in the face of changing environmental conditions.

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.
