Summary
Watershed Site H-3 is a critical water resource managed by the local government. This earth dam, completed in 1966, serves multiple purposes including fire protection, stock watering, and small fish pond creation, as well as flood risk reduction. With a height of 42 feet and a storage capacity of 134 acre-feet, this dam plays a crucial role in managing water flow in the TR-Soldier River.
Managed by the Iowa Department of Natural Resources, this site is regulated and inspected regularly to ensure its structural integrity and functionality. Despite its low hazard potential, the dam is considered to have a moderate risk level, prompting the implementation of risk management measures to safeguard the surrounding communities and environment. With a drainage area of 1.07 square miles and a surface area of 5.6 acres, this watershed site is a key component of the local water management infrastructure.
The Davis-Battle Cr. Watershed Site H-3 is a testament to the collaborative efforts of the USDA NRCS, local government, and state regulatory agencies in safeguarding water resources and mitigating flood risks in the area. As climate change continues to impact water availability and quality, the importance of such structures in sustainable water management practices cannot be overstated. Enthusiasts and stakeholders alike can find inspiration in the dedication to conservation and protection demonstrated by the various agencies involved in the management of this watershed site.

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.
