Summary
Built in 1959, this dam stands at a height of 31 feet and has a storage capacity of 58 acre-feet. Managed by the Natural Resources Conservation Service, the dam is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets state inspection, enforcement, and permitting requirements.
With a low hazard potential and a condition assessment of "Not Rated," Rae Number 2 serves as a vital water resource infrastructure in the region. Although the dam has not been inspected recently, it is designed to withstand maximum discharges of up to 945 cubic feet per second. Despite its age, the dam continues to provide essential water storage and flood control benefits to the surrounding area.
As climate change continues to impact water resources and infrastructure, the importance of maintaining and monitoring dams like Rae Number 2 becomes increasingly crucial. With its strategic location along the TR-BAD River and its capacity to mitigate flood risks, this earth dam plays a significant role in water management efforts in South Dakota. As water resource and climate enthusiasts, it is essential to stay informed about the condition and regulation of key structures like Rae Number 2 to ensure the resilience of our water systems in the face of a changing climate.

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.
