Summary
Completed in 1955, this earth dam stands at a height of 30 feet and spans a length of 600 feet. Its primary purposes include fire protection, stock, and serving as a small fish pond, with a storage capacity of 72 acre-feet. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected, permitted, and enforced by state authorities, ensuring its compliance with safety and environmental standards.
Situated on the TR-Muggins Creek, Bar 69 #4 has been designated with a low hazard potential and has not been rated for its current condition. While the dam has not been assessed for its risk management measures or emergency action plans, it remains under the jurisdiction of the state of Montana for any necessary interventions. With its location in Congressional District 00 and representation by Congressman Greg Gianforte, the dam plays a crucial role in providing water resources for fire protection and livestock, highlighting the importance of its maintenance and regulatory oversight in the face of changing climate conditions.
As water resource and climate enthusiasts continue to monitor the impact of dams on ecosystems and water availability, Bar 69 #4 serves as a focal point for understanding the intersection of human infrastructure and environmental sustainability. Its historical significance, coupled with its functional purposes, underscores the need for ongoing evaluation and management to ensure the safety and efficiency of water resources in the region. With state regulators overseeing its operations and maintenance, Bar 69 #4 remains a vital component of the water infrastructure in Rosebud County, Montana.

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.
