Summary

This sewage disposal pond, completed in 1954, serves as an offstream storage facility for wastewater from the city, with a storage capacity of 437 acre-feet. Positioned near the Yellowstone River, this earth dam structure stands at 9 feet in height and stretches 250 feet in length.

Despite being categorized as having low hazard potential and not yet rated for condition assessment, Miles City Sewage Disposal Pond #3 remains an essential component of the city's wastewater management system. With state regulatory oversight from DNRC and regular inspections in place, the pond ensures the safe disposal and storage of sewage. As an Earth dam type structure, it also plays a role in environmental protection and water resource management in the region.

As water resource and climate enthusiasts, understanding the significance of facilities like Miles City Sewage Disposal Pond #3 is crucial in safeguarding water quality and sustainability. With its location in the Omaha District and under Congressional representation of Greg Gianforte, this pond serves as a reminder of the interconnectedness between urban infrastructure, natural waterways, and regulatory frameworks in maintaining environmental integrity.

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.
