Summary
Built in 1969, the dam stands at a height of 15 feet with a length of 250 feet, providing a maximum storage capacity of 50 acre-feet. Despite its low hazard potential, the dam is regulated, permitted, inspected, and enforced by the South Dakota Department of Agriculture and Natural Resources, ensuring its safety and compliance with state regulations.
Owned and maintained by a private entity, Diamond Ring Ranch #3 serves as a crucial water resource for its surrounding area, with a normal storage capacity of 25 acre-feet. Although the dam's condition is currently listed as "Not Rated," it underwent its last inspection in November 1997. The presence of this dam contributes to the overall water management and climate resilience efforts in the region, highlighting the importance of maintaining and monitoring such structures for sustainable water utilization and environmental protection.
With its strategic location and purposeful design, Diamond Ring Ranch #3 reflects the intersection of water resource management, climate adaptation, and regulatory oversight in South Dakota. As part of the St. Paul District of the US Army Corps of Engineers, the dam's presence underscores the collaborative efforts between private owners and state agencies to ensure the safety, functionality, and resilience of water infrastructure 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.
