Summary
Situated on Bensley Creek, this dam has a height of 22 feet and a storage capacity of 75 acre-feet, with a normal storage level of 32 acre-feet. Despite being classified as having a low hazard potential and not being rated for condition assessment, Glasscock #2 is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes regular state inspections, permitting, and enforcement.
Owned and operated by private entities, Glasscock #2 serves as a crucial water resource in Custer County, Montana. Its strategic location within the Omaha District and Congressional District 00 ensures effective management and oversight. With a primary purpose of providing essential services like fire protection and stock water supply, this dam plays a vital role in supporting local agriculture and ensuring environmental sustainability along Bensley Creek.
Although lacking specific details on the condition assessment and emergency action plan, Glasscock #2 stands as a key infrastructure for water management in the region. With its historical significance dating back to 1954 and its continuous operation for over half a century, this earth dam remains a significant asset for the community, showcasing the importance of water resource management in the face of changing climate patterns and increasing water demands.

Dam Data Reference
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.
