Summary
Built in 1957, this dam serves multiple purposes, including fire protection, stock watering, and creating a small fish pond. With a height of 12 feet and a storage capacity of 89 acre-feet, Downy is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected regularly for safety and compliance.
Despite being classified as having a low hazard potential, the condition of Downy has not been rated, and there is limited information available about its emergency preparedness measures. The dam's primary purpose and design make it a valuable resource for water management in the region, providing essential services for both human and wildlife needs. As an important component of the local water infrastructure, maintaining and monitoring Downy is crucial to ensuring its continued functionality and safety for the community.
Located in Dawson County, Downy is situated within Congressional District 00 of Montana, under the representation of Greg Gianforte. As a vital part of the water management system in the area, Downy plays a significant role in supporting fire protection efforts, livestock watering, and ecological conservation. With its historical significance dating back to the 1950s, the dam stands as a testament to the importance of sustainable water resource management in the face of changing climate patterns and increasing water demands.

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.
