Summary
Built in 1953, this dam stands at a height of 15 feet and has a storage capacity of 108 acre-feet. Situated on the TR-E Fork Little Porcupine Creek, Vt #1 serves as a crucial asset for water resource management in the region.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Vt #1 is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. With a low hazard potential and a current condition assessment of 'Not Rated,' this dam plays a vital role in water supply and emergency preparedness for the surrounding area. Despite its age, Vt #1 continues to serve its intended purposes effectively.
The dam's location in Congressional District 00, Montana, under the oversight of Representative Greg Gianforte (R), highlights its significance in the local community. As climate change impacts water resources and poses new challenges, Vt #1 remains a crucial infrastructure for mitigating risks and ensuring water security in the region. As water resource and climate enthusiasts, understanding and monitoring the condition of dams like Vt #1 is essential for sustainable water management and resilience in the face of changing environmental conditions.

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.
