Summary
Built in 1956, this earth dam stands at 19 feet high and spans 375 feet in length, with a storage capacity of 56 acre-feet. With a primary purpose of providing fire protection, stock, and a small fish pond, this structure serves as a vital resource for the local community.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Montana #3 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the dam has not been inspected recently, it is equipped with state-of-the-art safety measures and is under state jurisdiction for permitting, inspection, and enforcement. In the event of an emergency, the dam has emergency action plans in place to ensure the safety of surrounding areas.
Situated in Rosebud County, Montana #3 is a crucial component of the local water resource and climate management infrastructure. With its strategic location and purpose, this dam plays a key role in providing essential services to the community while ensuring the safety and well-being of residents in the event of an emergency.

Dam Data Reference
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.
