Summary

Built in 1970 by the Natural Resources Conservation Service, this earth dam stands at 14 feet in height and spans 750 feet in length. With a storage capacity of 67 acre-feet, it serves as a crucial water resource for the area, providing a normal storage of 30 acre-feet and a maximum discharge capacity of 4,500 cubic feet per second.

Despite its age, Sd Noname 24 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam is regulated by the South Dakota Department of Environment and Natural Resources and undergoes regular inspection, permitting, and enforcement to ensure its safety and integrity. With its important role in water management and conservation, Sd Noname 24 remains a key infrastructure for the region, supported by federal agency funding and oversight.

As a vital component of the local water infrastructure, Sd Noname 24 plays a critical role in flood control and water supply management in Haakon County. While its exact purposes and primary function are not specified, the dam's presence along the TRIB-BAD RIVER highlights its importance in protecting the surrounding community from potential flooding events. With its low hazard potential and ongoing regulatory oversight, Sd Noname 24 continues to be a reliable and essential asset for water resource enthusiasts and climate advocates in the region.

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.
