Summary
Managed by the local government and regulated by the Iowa Department of Natural Resources, this dam has a storage capacity of 71 acre-feet and serves a drainage area of 1.43 square miles. Despite its small size, the dam plays a crucial role in water resource management in the region, particularly for fire protection and agricultural purposes.
Located in the city of Atlantic, Troublesome Cr Watershed Site 47-5 is situated along the Troublesome Creek and has not been rated for its condition assessment as of yet. With a moderate risk level of 3, the dam is categorized as having low hazard potential. The dam's spillway is uncontrolled, with a height of 17 feet and a normal storage capacity of 2 acre-feet. Although the dam has not been modified in recent years and lacks an emergency action plan, it remains a vital piece of infrastructure for the local community.
As an essential component of the water resource infrastructure in Audubon County, Troublesome Cr Watershed Site 47-5 highlights the importance of small dams in supporting various purposes such as fire protection and agricultural needs. With ongoing inspections and regulatory oversight from the Iowa DNR, this dam continues to play a significant role in managing water resources and mitigating potential risks for the surrounding community.

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.
