Summary
Constructed in 1958, this dam along the TR Moreau River stands at a height of 21 feet and has a storage capacity of 101 acre-feet. Managed by the Natural Resources Conservation Service, Leland Edwards serves as a vital resource for water storage and management in the region.
With a low hazard potential and a current condition assessment of "Not Rated," Leland Edwards plays a crucial role in flood control and water supply for the surrounding area. While not under the jurisdiction of the US Army Corps of Engineers, this dam is regulated, inspected, and enforced by the South Dakota Department of Environment and Natural Resources. Despite lacking an official emergency action plan and inundation maps, Leland Edwards continues to provide essential water resource management benefits to the community.
As a key structure in the region, Leland Edwards contributes to the sustainability of water resources and climate resilience in South Dakota. With its strategic location and storage capacity, this dam plays a significant role in managing water flow, particularly during periods of high discharge. While there are areas for improvement such as the development of an emergency action plan, Leland Edwards remains a vital component of the local water infrastructure, ensuring the safety and security of the community in the face of changing climate conditions.

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.
