Summary
Built in 1950, the dam stands at a height of 25 feet and serves multiple purposes including fire protection, stock, and a small fish pond. With a storage capacity of 65 acre-feet, the dam primarily caters to the needs of the local community while also offering recreational opportunities.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), L Galt #24 has a low hazard potential and is currently in a not rated condition assessment status. Despite its age, the dam continues to provide essential services and remains under state jurisdiction for regulation, inspection, and enforcement. Located in Garfield County, this structure plays a vital role in water resource management and climate resilience efforts in the region.
As a part of the broader water infrastructure in Montana, L Galt #24 contributes to the overall water security and conservation efforts in the state. With its modest size and multi-purpose design, the dam serves as a testament to the importance of sustainable water management practices for both human and environmental needs. Enthusiasts of water resources and climate resilience can find inspiration in the continued functionality and significance of structures like L Galt #24 in supporting local communities and ecosystems.

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.
