Summary
This dam stands at a height of 15 feet and has a storage capacity of 88 acre-feet, with a normal storage level of 60 acre-feet. With a surface area of 11 acres and draining an area of 80 square miles, Prater Dam South serves as a crucial water resource for the surrounding agricultural land.
Managed by private owners, this dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While details about the dam's construction year and spillway type are not provided, its design as an earth dam with buttress core types suggests a sturdy structure. The dam has not undergone recent inspections or assessments related to emergency action plans, inundation maps, or risk management measures, indicating a potential area for improvement in terms of safety and preparedness.
Despite its modest specifications, Prater Dam South plays a vital role in supporting irrigation activities in the region. As an enthusiast of water resources and climate, monitoring the condition and maintenance of this dam can provide insights into the challenges and opportunities for sustainable water management in Audrain County, Missouri.

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.
