Summary
The dam, completed in 1950, stands at a height of 27 feet and has a length of 700 feet. It has a normal storage capacity of 276 acre-feet and a maximum storage of 324 acre-feet. The dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources, ensuring that it meets state standards for safety and environmental compliance.
Despite being classified as a low hazard potential structure, Sagebrush has not been rated for its condition assessment. The dam does not have an Emergency Action Plan (EAP) prepared or updated, and there is no information available on the risk assessment or management measures in place. While the dam has not been modified in recent years, it is subject to regular inspections to ensure its continued safety and functionality. The Little Missouri River tributary is the primary water source for the dam, which is overseen by the Omaha District of the US Army Corps of Engineers.
Water resource and climate enthusiasts interested in the infrastructure of water management systems in South Dakota may find Sagebrush to be a fascinating case study. With its historical construction in 1950 and ongoing regulatory oversight, this earth dam serves as a vital component of the local water supply and flood control efforts. The dam's location in Harding County, with its low hazard potential and lack of recent modifications, presents an intriguing opportunity for further study and analysis in the realm of water resource management and climate resilience.

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.
