Summary
This structure on TR-Brown Creek has a dam height of 17 feet and a length of 360 feet, providing a storage capacity of 66 acre-feet. While the dam is categorized as having a low hazard potential, its current condition is not rated, indicating a need for further assessment to ensure its safety and functionality for the surrounding community.
Despite being state regulated and permitted by the Montana Department of Natural Resources and Conservation (DNRC), Powell #2 has not undergone recent inspections or maintenance. With its proximity to the Omaha District and Congressional District 00 in Montana, it is crucial for stakeholders to prioritize the assessment and potential rehabilitation of this dam to prevent any unforeseen risks or emergencies. Climate enthusiasts and water resource experts should monitor the progress of any future evaluations or improvements to ensure the sustainable management of this essential infrastructure for water storage and fire protection in the region.
As water resources and climate change continue to impact infrastructure like Powell #2, it is essential for state agencies and private owners to collaborate on effective monitoring and maintenance practices. By investing in regular inspections and updates to emergency action plans, stakeholders can mitigate potential risks and ensure the long-term resilience of dams like Powell #2 in the face of evolving environmental conditions. Through proactive measures and community engagement, this dam can continue to serve its intended purposes while safeguarding the surrounding area from water-related hazards.

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.
