Summary

This earth dam stands at 33 feet high and stretches 400 feet in length, with a storage capacity of 26 acre-feet. While the dam is classified as low hazard potential, it is considered to have a moderate risk level, indicating the need for ongoing monitoring and maintenance.

Situated on the Tr- Iowa River, the Marengo Golf & Country Club Dam plays a crucial role in managing water resources in the region. Despite not being regulated or inspected by the state, the dam remains an essential structure for irrigation purposes. With its uncontrolled spillway and soil foundation, the dam is designed to withstand potential risks and ensure the safety of surrounding areas.

As water resource enthusiasts and climate advocates, it is important to recognize the significance of structures like the Marengo Golf & Country Club Dam in sustaining agricultural activities and managing water flow in the region. By understanding the design, purpose, and risk assessment of such dams, enthusiasts can contribute to efforts aimed at enhancing water resource management and climate resilience in Iowa.

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.
