Summary
Completed in 1969, this dam has a height of 25 feet and a length of 750 feet, with a storage capacity of 400 acre-feet. Despite its low hazard potential, the dam is regulated by the South Dakota Department of Agriculture and Natural Resources, with regular inspections and enforcement measures in place to ensure its safety and integrity.
Managed by the Natural Resources Conservation Service, Diamond Ring Ranch #6 plays a crucial role in water resource management in the region, providing flood control and water storage for agricultural purposes. Its location within the St. Paul District adds to its significance, with a maximum discharge capacity of 2100 cubic feet per second. While the dam's condition assessment is currently listed as "Not Rated," its history of proper maintenance and state regulation indicates a commitment to its ongoing safety and functionality.
With its strategic positioning and historical significance, Diamond Ring Ranch #6 stands as a testament to the importance of proper dam management in ensuring water resource sustainability and climate resilience. As a key infrastructure piece in South Dakota, this dam serves as a vital component in managing water flows and protecting downstream areas, while also highlighting the collaborative efforts between private owners and state agencies in maintaining the region's water infrastructure.

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.
