Summary

This facility, completed in 1950, features an earth dam with a height of 8 feet and a length of 2240 feet, providing a storage capacity of 155 acre-feet for sewage disposal purposes. Situated along the Poplar River-offstream, this low-hazard structure is regulated and inspected by the Montana Department of Natural Resources and Conservation to ensure compliance with state environmental regulations.

Despite not having a designated surface area or drainage area, the Scobey Sewage Disposal Ponds play a vital role in wastewater management for the city of Poplar. With a normal storage capacity of 124 acre-feet, this facility operates under the supervision of the local government to maintain water quality and prevent environmental contamination. While the dam's condition is currently not rated, it serves as a crucial component in the city's infrastructure for sewage treatment and disposal, contributing to the overall water resource management efforts in the region.

As climate change continues to impact water resources globally, the importance of well-maintained sewage disposal infrastructure like the Scobey Sewage Disposal Ponds cannot be overstated. With state-regulated operations, regular inspections, and low-hazard potential, this facility exemplifies the commitment to sustainable water management practices in the face of evolving environmental challenges. Enthusiasts of water resources and climate resilience can appreciate the role that structures like the Scobey Sewage Disposal Ponds play in safeguarding water quality and protecting ecosystems in Montana.

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.
