Summary
With a primary purpose of fire protection, stock, or small fish pond, this structure also serves as flood risk reduction for the area. The dam stands at 33 feet high and spans 480 feet, providing a storage capacity of 70 acre-feet and covering a surface area of 4.3 acres.
Located on TR-FOUR MILE CR., this dam is regulated by the Iowa Department of Natural Resources and undergoes regular state inspections, enforcement, and permitting. Despite being classified as having a low hazard potential and a moderate risk assessment, the condition assessment of the dam is currently marked as "Not Rated". Troublesome Cr Watershed Site 48-5 is essential for water resource management in the region and plays a crucial role in maintaining the ecological balance of the area.
Water resource and climate enthusiasts will find Troublesome Cr Watershed Site 48-5 to be a fascinating case study in dam infrastructure and management. With its unique combination of purposes, including fire protection and flood risk reduction, this earth dam serves as a vital resource for the community of Atlantic, Iowa. As efforts continue to assess and manage the risk associated with the dam, stakeholders must stay vigilant in ensuring its long-term sustainability and effectiveness in water resource management.

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.
