Summary
Reedy, located in Perkins, South Dakota, is a privately owned earth dam constructed in 1962 by the Natural Resources Conservation Service. With a height of 13 feet and a length of 830 feet, this dam has a storage capacity of 197 acre-feet and serves as a vital water resource in the region. It is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement protocols in place to ensure its safety and functionality.
Despite being classified as having a low hazard potential and currently rated as "Not Rated" for condition assessment, W. Reedy plays a crucial role in managing water flow along the TR-MOREAU river stream. It is designed to withstand a maximum discharge of 165 cubic feet per second and has a normal storage capacity of 150 acre-feet. While the dam has not been inspected recently, the state jurisdiction and regulatory agency are actively involved in overseeing its operation and maintenance.
The dam's Emergency Action Plan status, risk assessment, and management measures are currently not available, indicating a potential area for improvement in the future. Overall, W. Reedy stands as a testament to the importance of sustainable water resource management and climate resilience in South Dakota, highlighting the collaborative efforts between private owners, federal agencies, and state regulators to ensure the safety and integrity of critical infrastructure 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.
