Summary

Constructed in 1975 by the USDA NRCS, this earth dam stands at a height of 29 feet and has a length of 328 feet, providing a storage capacity of 38 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources and is inspected regularly for safety and compliance.

Despite its low hazard potential, Randall Rc&D #124 plays a crucial role in managing water resources in the area, with a maximum discharge capacity of 668 cubic feet per second. The dam's location on the TRIB. MISSONot RatedI RIVER contributes to the overall water management strategy in the region. As a state-regulated structure, it undergoes inspections, enforcement measures, and permitting to ensure its safety and functionality.

As a vital component of the local water infrastructure, Randall Rc&D #124 serves as a valuable resource for water resource and climate enthusiasts interested in sustainable water management practices. With its carefully designed structure and regulatory oversight, this dam exemplifies the importance of responsible water resource management in addressing the challenges posed by climate change and increasing water demands.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
