Summary
This site, located in Atlantic, Iowa, along the Troublesome Creek, plays a crucial role in controlling erosion and sedimentation, ultimately benefiting the overall health of the watershed. Completed in 2003, this Earth dam stands at a height of 25 feet and has a storage capacity of 56 acre-feet, with a primary purpose of Grade Stabilization.
Managed by the Iowa DNR, Troublesome Creek Watershed Site 29-1 is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and compliance with safety standards. With a low hazard potential and a moderate risk assessment rating, this site is well-maintained and poses minimal risks to the surrounding community. As part of the Rock Island District, this dam is essential for flood control and water management in the region, highlighting the importance of sustainable infrastructure for climate resilience.
Overall, Troublesome Creek Watershed Site 29-1 serves as a critical infrastructure project that showcases the collaborative efforts between local government, federal agencies, and environmental designers to protect water resources and mitigate climate-related risks. With its strategic location, purposeful design, and state-regulated management, this Grade Stabilization dam stands as a model for sustainable watershed management practices in Iowa, ensuring the long-term health and sustainability of Troublesome Creek and its surrounding ecosystem.

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.
