Summary

and completed in 1999. This earth dam stands at a height of 26 feet and has a length of 566 feet, creating a reservoir with a storage capacity of 86 acre-feet. The dam serves multiple purposes including fire protection, stock watering, and small fish pond management, making it a crucial resource for the local community.

Managed by the Iowa Department of Natural Resources, Trinkle Reclamation Dam C is regulated, permitted, inspected, and enforced by the state, ensuring its safe operation and compliance with environmental regulations. The dam is classified as low hazard potential with a moderate risk assessment level, indicating a need for ongoing monitoring and maintenance to mitigate potential risks. Its location on TR-Cedar Creek in Marion County, Iowa, contributes to the local watershed by providing water storage and flood control benefits.

Water resource and climate enthusiasts will appreciate the role of Trinkle Reclamation Dam C in enhancing water security and ecosystem resilience in the region. With its strategic placement and moderate risk management measures, the dam stands as a testament to sustainable water management practices. As a vital piece of infrastructure for fire protection, livestock support, and wildlife habitat, this dam exemplifies the intersection of human needs and environmental stewardship in water resource management.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
