Summary
Situated on the TR-Redwater River, this dam has a height of 20 feet and a storage capacity of 68 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," Shefelbine serves as a vital resource for water management in the area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Shefelbine is subject to state regulation, permitting, inspection, and enforcement. Despite its age, the dam has not undergone any modifications in recent years and lacks specific details on its surface area, drainage area, and spillway type. The dam's emergency preparedness and risk assessment measures remain unclear, highlighting the need for further evaluation and potential updates to ensure its continued safety and functionality.
Shefelbine's location in Poplar, Montana, makes it a key structure for water resource management in the region, providing essential services for fire protection and agricultural needs. As climate change continues to impact water availability and usage, Shefelbine's role in maintaining water security and resilience in the face of evolving environmental conditions becomes increasingly important. With its low hazard potential and state regulation, Shefelbine stands as a testament to effective water resource management and the need for ongoing monitoring and evaluation to ensure its continued safety and operational efficiency.

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.
