Summary
Constructed in 1951, this earth dam stands at 19 feet high and spans 360 feet in length, with a storage capacity of 120 acre-feet. Managed by the Natural Resources Conservation Service, Leland Edwards is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that state permitting, inspection, and enforcement are in place to maintain its integrity.
With a low hazard potential and a condition assessment of "Not Rated," Leland Edwards provides essential water resource management for the region. While the dam has not been modified in recent years and lacks certain safety measures such as an Emergency Action Plan, it remains a key infrastructure for flood control and water storage along the TR Moreau River. Located within the Omaha District of the US Army Corps of Engineers, Leland Edwards contributes to the overall water resource management efforts in South Dakota.
For water resource and climate enthusiasts, Leland Edwards serves as a notable example of private ownership in dam infrastructure. Its historical significance, combined with its role in water storage and flood control, highlights the importance of proper regulation and maintenance to ensure the safety and functionality of such structures. As climate change continues to impact water resources, understanding the management and condition of dams like Leland Edwards is essential for sustainable water resource management 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.
