Summary
Built in 1959, this dam serves multiple purposes including fire protection, stock, and a small fish pond, with a storage capacity of 128 acre-feet. Situated on the TR-FLY CREEK, this structure has a low hazard potential and has not been rated for its condition assessment.
Operated under the jurisdiction of the Montana Department of Natural Resources and Conservation (DNRC), J R Scott #8 is regularly inspected, permitted, and enforced to ensure its safety and compliance with state regulations. Despite its age, this dam has not undergone any modifications over the years and lacks certain risk management measures such as emergency action plans and inundation maps. The dam's location and purpose make it an essential part of the local water resource infrastructure, providing valuable fire protection and water storage for the community.
For water resource and climate enthusiasts, J R Scott #8 represents a unique example of a privately owned dam contributing to both local water management and environmental conservation efforts. With its historical significance and functional importance, this earth dam serves as a reminder of the essential role that water infrastructure plays in sustaining ecosystems and supporting various human activities in the region. As efforts continue to address climate change and water resource challenges, structures like J R Scott #8 will be crucial in ensuring the resilience and sustainability of water systems for future generations.

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.
