Summary
Completed in 1937, this reservoir has a dam height of 20 feet and a storage capacity of 74 acre-feet. Situated on Frozen Dog Coulee, the reservoir has a low hazard potential and is regulated by the Montana Department of Natural Resources and Conservation (DNRC).
Despite not being rated for its condition, Glasscock Reservoir #2 is regularly inspected, permitted, and enforced by state agencies, ensuring its safe operation and maintenance. The reservoir's location in a remote area with no nearby town highlights its importance for local fire protection and agricultural needs. With a maximum storage capacity of 74 acre-feet and normal storage of 45 acre-feet, the reservoir plays a crucial role in ensuring water availability for various uses in the region.
Managed by private owners, Glasscock Reservoir #2 represents a vital water resource in Montana, contributing to the sustainability of the local ecosystem and supporting agricultural activities. With its historical significance dating back to the 1930s, the reservoir continues to serve its intended purposes while being regulated and monitored by state authorities to ensure its safety and efficiency for the community.

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.
