Summary
Completed in 1976, this Earth dam stands at 37 feet tall and spans 548 feet in length, providing a storage capacity of 264 acre-feet. The dam serves multiple purposes including flood risk reduction, demonstrating its importance in managing water resources in the region.
Located in a low hazard area with a moderate risk assessment score of 3, Troublesome Cr Watershed Site 84-2 is regulated by the Iowa DNR and undergoes regular inspection, permitting, and enforcement to ensure its structural integrity and functionality. The dam's uncontrolled spillway type and soil foundation contribute to its overall design and operational characteristics. Despite being not rated for condition assessment, the site remains crucial for water management and conservation efforts in the region.
With its location along the TR-EAST NISHNABOTNA river and a drainage area of 0.7 square miles, Troublesome Cr Watershed Site 84-2 plays a vital role in water management and conservation efforts in Audubon, Iowa. As a valuable asset for fire protection, stock, and small fish pond purposes, the site highlights the importance of sustainable water resource management practices in mitigating flood risks and supporting ecosystem health in the region.

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.
