Summary
Watershed Site G-2 is a vital water resource managed by the local government for fire protection, stock, and small fish pond purposes. Constructed in 1966 by the USDA NRCS, this earth dam stands at a height of 27 feet and spans a length of 414 feet, with a storage capacity of 84 acre-feet. The dam serves to reduce flood risks in the area, while also supporting the ecological health of the TR-Soldier River.
Managed by the Iowa DNR, this dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment rating, the Davis-Battle Cr. Watershed Site G-2 plays a crucial role in water management and conservation efforts in the region. As part of the Rock Island District, this site serves as a key infrastructure for water resource enthusiasts and climate advocates alike.
With its strategic location, structural design, and environmental impact, the Davis-Battle Cr. Watershed Site G-2 stands as a testament to the importance of sustainable water resource management and climate resilience. As stakeholders work together to monitor, assess, and maintain this critical infrastructure, the site continues to play a crucial role in protecting communities, wildlife, and ecosystems from the impacts of floods and other water-related challenges in Monona County, Iowa.

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.
