Summary
Managed by the local government and regulated by the Iowa DNR, this structure on TR- Nishnabotna River serves a vital role in flood risk reduction for the surrounding area. With a storage capacity of 50 acre-feet and a drainage area of 0.2 square miles, this dam plays a crucial role in managing water resources in the region.
Despite being classified as low-hazard, this dam has a moderate risk assessment rating of 3, suggesting some potential vulnerabilities that need to be addressed. The condition assessment is currently listed as "Not Rated", indicating a need for further evaluation of the structure's safety and integrity. With no emergency action plan in place, it is essential for authorities to prioritize the development of a comprehensive strategy to ensure the safety of downstream communities in case of a dam failure.
As water resource and climate enthusiasts, it is important to monitor and advocate for the maintenance and improvement of structures like Troublesome Cr Watershed Site 83-1 to ensure the sustainable management of water resources and protection of communities in the face of changing climate conditions. By staying informed and engaged in the regulation and inspection processes of such critical infrastructure, we can play a role in safeguarding our environment and enhancing resilience to water-related challenges in the future.

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.
