Summary

Designed by the USDA NRCS and completed in 1985, this earth dam stands at a height of 31 feet and spans a length of 719 feet, with a storage capacity of 237 acre-feet and a surface area of 10.2 acres. With a drainage area of 0.68 square miles, the dam serves to reduce flood risks in the region.

Managed by the Iowa DNR, this site is subject to state regulation, inspection, and enforcement. Despite its low hazard potential, the dam's condition remains unrated, and risk assessment indicates a moderate level of risk with a DSAC assigned date yet to be determined. While emergency action plans are not explicitly mentioned, the presence of spillways and uncontrolled outlets suggests a level of preparedness for potential emergencies. Overall, the Badger Creek Watershed Site 48-2 plays a crucial role in water resource management and climate resilience efforts in the region, reflecting a collaborative approach between local and federal agencies to safeguard the community against natural disasters.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
