Summary
Constructed in 1958, this dam stands at a height of 26 feet and has a length of 468 feet. It has a storage capacity of 29 acre-feet and a maximum discharge of 756 cubic feet per second. Despite its low hazard potential, the condition of Rae Number 3 has not been rated as of the last inspection in May 2002.
Managed by the Natural Resources Conservation Service, Rae Number 3 plays a crucial role in regulating the flow of the TR-Bad River. With state oversight and enforcement in place, this dam serves as a vital water resource infrastructure in the region. Its emergency action plan status and risk assessment remain unknown, suggesting the need for further evaluation and preparedness measures to ensure the safety and effectiveness of Rae Number 3 in the face of evolving climate and water resource challenges.
For water resource and climate enthusiasts, Rae Number 3 presents an intriguing case study of a mid-20th century earth dam in the heart of South Dakota. Its location, design, and regulatory framework offer insights into the intersection of infrastructure, environmental stewardship, and emergency preparedness. As discussions around water security and climate resilience continue to gain prominence, understanding the role and condition of dams like Rae Number 3 becomes increasingly important for sustainable water management practices in the region.

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.
