Summary
Completed in 1958, this earth dam stands at a height of 16 feet and has a storage capacity of 99 acre-feet. The primary purpose of the dam is irrigation, serving the surrounding agricultural land in Custer County. The structure is regulated by the Montana Department of Natural Resources and Conservation (DNRC), ensuring regular inspections and enforcement of safety measures.
Situated on the Steiger Creek, Clark (Custer) Dam is identified as having a low hazard potential and its condition is currently not rated. Despite its age, the dam has not undergone any major modifications or assessments in recent years. The emergency action plan for the dam is also not updated, raising questions about its readiness for potential disasters. Overall, Clark (Custer) Dam serves as a vital water resource for the region, highlighting the importance of continued monitoring and maintenance to ensure its safety and efficiency for irrigation purposes.
With its location in a key agricultural area and under the jurisdiction of the state of Montana, Clark (Custer) Dam plays a crucial role in supporting local water management efforts. As climate change continues to impact water resources, the proper regulation and maintenance of dams like Clark (Custer) become increasingly important to ensure sustainable water supply for agricultural activities in the region. As enthusiasts of water resources and climate, it is essential to monitor and advocate for the safety and efficiency of dams like Clark (Custer) to secure the water supply for future generations.

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.
