Summary
Completed in 1937, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. It has a height of 27 feet and a storage capacity of 1,470 acre-feet, with a normal storage level of 581 acre-feet. The dam is situated on the SOUTH FORK COAL BANK CREEK and is regulated by the Montana Department of Natural Resources and Conservation (DNRC).
With its significant hazard potential, Sand Rock is a crucial water resource in the region, providing essential services for both human and ecological needs. The dam has not been rated for its condition assessment, and there is limited information available on its maintenance and emergency preparedness measures. Located in a remote area, the dam's purpose and design reflect the historical context of water management practices in the region, serving as a reminder of the importance of sustainable water resource management in the face of changing climate patterns.
As climate change continues to impact water resources worldwide, understanding the role of structures like Sand Rock in local water management becomes increasingly important. With its proximity to Congressional District 00 in Montana, the dam represents a piece of the region's water infrastructure that must be maintained and monitored for the safety and well-being of surrounding communities and ecosystems. As enthusiasts for water resources and climate resilience, staying informed about structures like Sand Rock is essential for advocating for sustainable water management practices in the face of a changing climate.

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.
