Summary
With a dam height of 45 feet and a storage capacity of 159 acre-feet, this site serves as a vital component for flood risk reduction in the area. The dam overlooks the TR-East Nishnabotna River and covers a surface area of 6 acres, with a drainage area of 0.35 square miles.
Managed by the local government and regulated by the Iowa DNR, Troublesome Cr Watershed Site 84-3 has a low hazard potential and a moderate risk assessment score of 3. Despite not being rated for condition assessment, the dam continues to meet the necessary state regulations for permitting, inspection, and enforcement. With its uncontrolled spillway type and no outlet gates, the site presents a stable structure that contributes to the overall water resource management and environmental conservation efforts in the region.
In collaboration with federal agencies like the Natural Resources Conservation Service, Troublesome Cr Watershed Site 84-3 stands as a testament to effective water resource management and climate resilience. As water resource and climate enthusiasts, it is essential to monitor and support the maintenance of such critical infrastructure to ensure the continued safety and sustainability of our water systems.

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.
