Summary
Built in 1950, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 15 feet and a length of 1400 feet, Transistor #1 has a storage capacity of 232 acre-feet, with a normal storage level of 119 acre-feet. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected regularly for safety and compliance.
Despite being classified as having a low hazard potential, the condition assessment of Transistor #1 is currently listed as "Not Rated." This suggests that the dam's overall safety and structural integrity have not been fully evaluated. The emergency action plan (EAP) status, risk assessment, and risk management measures for the dam are also not available. It is important for water resource and climate enthusiasts to monitor the maintenance and assessment of Transistor #1 to ensure the safety and functionality of this crucial water management infrastructure in Montana.
Overall, Transistor #1 plays a significant role in providing water resources for fire protection, livestock, and fish habitat in the Savoy area. As a privately owned dam with state jurisdiction and regulation, it is essential for stakeholders and authorities to prioritize the assessment, maintenance, and emergency preparedness of this structure to ensure the continued sustainability and safety of water resources in the region. Monitoring and addressing any potential risks or deficiencies in the dam's condition will be essential for protecting both the environment and the community that relies on its services.

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.
