Summary

Constructed in 1992 by the USDA NRCS, this earth dam stands at a height of 31 feet and spans 502 feet in length, with a storage capacity of 101 acre-feet. The dam is regulated by the Iowa DNR and is designed to reduce flood risks in the area, serving as a crucial water resource for the community.

With a low hazard potential and a moderate risk assessment rating, Soap Creek Watershed Site 4-112 has not been inspected or assessed for its condition. Despite being in operation for almost three decades, the dam's emergency action plan status, as well as its risk management measures, remain unknown. Its location on TR-South Soap Creek and its purpose for fire protection make it a significant asset for both the environment and local stakeholders, highlighting the importance of continued monitoring and maintenance to ensure its effectiveness in water resource management and climate resilience efforts.

As a vital infrastructure for water management in the region, Soap Creek Watershed Site 4-112 represents a collaborative effort between local government agencies and the USDA NRCS. The dam's construction and purpose underscore the intersection of fire protection, stock management, and environmental conservation, providing a multifaceted solution for water resource challenges. With its regulated status and strategic location, this site serves as a testament to the importance of sustainable water management practices in mitigating climate-related risks and ensuring the resilience of communities in the face of changing environmental conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
