Summary
Built in 1960, this earth dam stands at a height of 15 feet and has a storage capacity of 176 acre-feet, primarily serving the purposes of fire protection, stock, and a small fish pond. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state jurisdiction, permitting, inspection, and enforcement in place to ensure its safety and compliance.
With a low hazard potential and a condition assessment of "Not Rated," Glasscock Bros #2 is a crucial water resource for the local community. While the dam has not been modified over the years and lacks certain detailed information such as spillway type and width, it continues to provide essential services to the area. The dam's emergency action plan status, risk assessment, and management measures are currently not available, indicating a potential area for improvement in ensuring the dam's resilience to climate change impacts and emergency situations.
Despite its limited information and assessment data, Glasscock Bros #2 remains an important infrastructure for water supply and management in Rosebud County, Montana. As climate change continues to pose challenges to water resources, it is essential for stakeholders to monitor and maintain the dam's safety and functionality to ensure a secure water supply for the community. Efforts to update and enhance the dam's emergency preparedness and risk management measures will be crucial in safeguarding this valuable water resource for the future.

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.
