Summary
Watershed Site C-12-1 is a vital water resource management site located in Monona, Iowa, along the TR-SOLDIER RIVER. This local government-owned earth dam was completed in 1964 with a primary purpose of fire protection, stock, or small fish pond, as well as flood risk reduction. With a dam height of 60 feet and a storage capacity of 70 acre-feet, this structure serves to safeguard the surrounding area from potential hazards while also providing essential water management benefits.
Managed by the USDA NRCS, this watershed site plays a crucial role in maintaining the ecological balance of the region. With a low hazard potential and a moderate risk assessment score of 3, efforts are continually being made to ensure the safety and functionality of the dam. Although the condition assessment is currently listed as "Not Rated," the state regulatory agency, IOWA DNR, is actively involved in permitting, inspecting, and enforcing regulations to uphold the integrity of the structure.
Water resource and climate enthusiasts can appreciate the significance of the Davis-Battle Cr. Watershed Site C-12-1 as a key component of the local water management infrastructure. With its strategic location and purposeful design, this earth dam contributes to the overall sustainability and resilience of the area. As efforts continue to enhance risk management and regulatory compliance, this site remains an essential resource for both flood control and ecosystem preservation in the Monona, Iowa 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.
