Summary
Completed in 1950, this earth dam stands at a height of 25 feet and spans 250 feet in length, with a maximum storage capacity of 140 acre-feet. Situated on the TR-Iowa River, the dam serves a primarily recreational purpose in addition to flood control.
Despite its low hazard potential, South Amana Pond Dam poses a moderate risk due to its condition assessment being "Not Rated." Emergency action plans and risk management measures are yet to be established for this structure, highlighting the need for proactive monitoring and maintenance. As water resource and climate enthusiasts, there is an opportunity to engage with local authorities to ensure the safety and sustainability of this vital infrastructure in the face of changing environmental conditions.
As we delve into the complexities of water resource management and climate resilience, South Amana Pond Dam serves as a case study for the intersection of human development and natural systems. By advocating for regular inspections, hazard assessments, and emergency preparedness, we can contribute to the long-term viability of this dam and protect the surrounding ecosystem. Let us work together to safeguard our water resources and mitigate the impacts of climate change on critical infrastructure like South Amana Pond Dam.

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.
