Summary

This site, completed in 1982, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. With a dam height of 26 feet and a storage capacity of 65 acre-feet, this site covers a surface area of 4.8 acres and has a drainage area of 0.2 square miles. The dam is primarily an earth structure with a soil foundation and an uncontrolled spillway type.

The Troublesome Cr Watershed Site 49-5 is regulated by the Iowa Department of Natural Resources and has a low hazard potential with a moderate risk assessment score of 3. Despite not being rated for condition assessment, this site is inspected, permitted, and enforced by state agencies. Located near TR-FOUR MILE CR., this site is crucial for water management and protection in the area. With its strategic design and purposeful functions, Troublesome Cr Watershed Site 49-5 stands as a vital resource for maintaining water quality, ensuring flood protection, and supporting local ecosystems in Atlantic, Iowa.

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.
