Summary

Standing at a height of 18 feet and stretching 620 feet in length, this dam plays a crucial role in managing water resources in the region. It is situated on a tributary of the Cheyenne River and has a maximum storage capacity of 57 acre-feet, providing essential water supply for the area.

Managed by the Natural Resources Conservation Service and regulated by the South Dakota Department of Environment and Natural Resources, Bomb Range Dam is classified as having a significant hazard potential. Despite not having a current condition rating, the dam is inspected, permitted, and enforced by state agencies to ensure its structural integrity and public safety. With a maximum discharge capacity of 2940 cubic feet per second, the dam serves as a vital flood control measure in the region.

While the dam's Emergency Action Plan status and risk assessment details are currently unavailable, Bomb Range Dam remains a critical infrastructure for water resource management and climate resilience in the area. Its strategic location and operational capacity make it a key asset in safeguarding against potential hazards and ensuring sustainable water supply for the community.

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.
