Summary

This facility, completed in 1960, serves the city of Great Falls and is situated along the TR-North Fork Smith River. The dam, primarily constructed of earth, stands at a height of 8 feet and has a storage capacity of 55 acre-feet.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), White Sulphur Springs Sewage Disposal has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While there is no recent data on inspection frequency or emergency action plans, the facility's operations are overseen by the state regulatory agency, ensuring compliance with state permitting, inspection, and enforcement requirements.

White Sulphur Springs Sewage Disposal represents a crucial infrastructure for managing wastewater in the region, serving as a vital component of environmental protection and public health. With its location in a scenic area along the TR-North Fork Smith River, the facility's low hazard potential and state-regulated status highlight the importance of responsible water resource management and climate-conscious sewage disposal practices in safeguarding the surrounding natural environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
