Summary
Watershed Site H-4-2 is a key water resource managed by local government authorities for fire protection, stock, and small fish pond purposes. Built in 1966 by USDA NRCS designers, this earth dam stands at a height of 47 feet and stretches over 419 feet, with a storage capacity of 80 acre-feet. The site is State regulated by the Iowa DNR and falls under the jurisdiction of the Iowa state agency, ensuring proper permitting, inspection, and enforcement measures are in place.
The dam's primary purpose also includes flood risk reduction, reflecting its crucial role in managing water resources in the region. The watershed site, situated along the TR-SOLDIER RIVER, covers a surface area of 3.5 acres and drains a 0.48 square mile area. Despite being classified as low hazard potential, the dam is deemed to have a moderate risk level, prompting the need for ongoing risk management measures. Overall, this site serves as a vital component of the local water infrastructure, contributing to both environmental resilience and community safety in the region.
As water resource and climate enthusiasts delve into the details of the Davis-Battle Cr. Watershed Site H-4-2, they uncover a complex network of regulatory oversight, design considerations, and risk management strategies. With its earth dam structure and controlled spillway, this site showcases the intricate balance between water conservation, agricultural needs, and flood protection. The ongoing monitoring and maintenance of this watershed site underscore the importance of sustainable water resource management practices in mitigating potential hazards and ensuring long-term environmental sustainability.

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.
