Summary
Built in 1965 by the USDA NRCS, this dam stands at 24 feet in height and spans 790 feet in length, with a storage capacity of 158 acre-feet. Its primary purpose is flood risk reduction, serving to protect the surrounding area from potential inundation during periods of high water flow.
The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state permitting, inspection, and enforcement in place to ensure its safe operation. With a significant hazard potential and a moderate risk assessment rating, the dam's condition is currently not rated, indicating a need for further assessment and potential risk management measures. The spillway is uncontrolled with a width of 125 feet, designed to handle a maximum discharge of 565 cubic feet per second.
Located in Poplar, Montana, Salsbury (Richland) plays a crucial role in mitigating flood risks in the region, underscoring the importance of effective water resource management and infrastructure maintenance in the face of a changing climate. Enthusiasts of water resources and climate resilience will find this dam's design and operational details intriguing, as well as the ongoing efforts to ensure its safety and effectiveness in protecting the local community from potential flood events.

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.
