Summary
Completed in 1987 by the USDA NRCS, this earth dam stands at a height of 35 feet and spans 760 feet, with a maximum storage capacity of 272 acre-feet. Situated along the TR- Troublesome Cr. stream, this dam covers a drainage area of 0.71 square miles and serves as a flood risk reduction measure for the community of Atlantic.
Despite its low hazard potential, Troublesome Cr Watershed Site 21-1 is not currently rated for its condition assessment, highlighting the need for ongoing monitoring and maintenance. The Iowa DNR plays a crucial role in regulating, inspecting, and enforcing state requirements for this dam, ensuring its operational safety and integrity. With a moderate risk assessment score of 3, it is essential for stakeholders to implement effective risk management measures to safeguard this important water infrastructure for the surrounding area.
As a significant component of the water management system in Cass County, Troublesome Cr Watershed Site 21-1 represents a critical asset for both water resource and climate enthusiasts. Its construction and maintenance by the USDA NRCS, along with state regulatory oversight by the Iowa DNR, demonstrate a collaborative effort to protect the community from flooding and provide essential water resources for various purposes. By staying informed and actively involved in the monitoring and maintenance of this dam, stakeholders can ensure its continued functionality and resilience in the face of changing environmental conditions.

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.
