Summary
Constructed in 1984 by the USDA NRCS, this earth dam stands at 33 feet tall with a length of 654 feet, providing a storage capacity of 142 acre-feet. The dam serves to reduce flood risks and is regulated by the Iowa Department of Natural Resources.
With a low hazard potential and a moderate risk assessment rating, Troublesome Cr Watershed Site 81-1 plays a crucial role in managing the water resources of the TR- East Nishnabotna River. The dam's condition is currently not rated, but it undergoes regular state inspections and enforcement to ensure its safety and functionality. While it lacks a formal Emergency Action Plan (EAP) and inundation maps, the dam's risk management measures are continuously evaluated to meet safety guidelines.
As a vital infrastructure for water resource management, Troublesome Cr Watershed Site 81-1 stands as a testament to the collaborative efforts of local government agencies and the USDA NRCS in safeguarding the community against potential water-related hazards. Its strategic location and purposeful design make it a key player in maintaining the ecological balance and protecting the surrounding areas from flooding events. This site serves as a tangible example of sustainable water management practices in action.

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.
