Summary
2, located in Monona County, Iowa, is a privately owned earth dam completed in 1974 for fire protection, stock, or small fish pond purposes. The dam stands at a height of 36 feet and has a length of 683 feet, providing a storage capacity of 91 acre-feet. Situated on TR-Soldier River, the dam covers a surface area of 4.2 acres with a drainage area of 0.53 square miles.
Managed by the USDA NRCS, the Spring Valley Project No. 2 is regulated by the Iowa Department of Natural Resources and undergoes regular inspections and enforcement to ensure its safety and compliance with state regulations. The hazard potential of the dam is rated as low, with a moderate risk assessment score of 3. While the condition of the dam is currently not rated, the risk management measures and emergency action plan for the site are not specified in the provided data.
The project does not have a designated emergency action plan or updated contact information for emergency response. Despite these gaps, the Spring Valley Project No. 2 serves as a vital resource for water management and conservation in the region, highlighting the importance of proper maintenance and oversight for sustainable use of water resources in the face of changing climate patterns.

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.
