Summary
The reservoir has a storage capacity of 64 acre-feet and a normal storage level of 39 acre-feet, serving as a vital resource for the local community. Situated on TR-Mud Creek, the reservoir plays a crucial role in maintaining water supply for irrigation, livestock, and emergency firefighting needs in the area.
With a dam height of 10 feet and a length of 300 feet, Road Reservoir has a low hazard potential and is currently in "Not Rated" condition. The State of Montana, through the DNRC, regulates and inspects the reservoir to ensure its safety and compliance with state guidelines. Despite not having a designated spillway or outlet gates, the reservoir continues to provide valuable water storage and management capabilities, contributing to the overall water resource infrastructure in the region.
Managed outside of federal oversight, Road Reservoir stands as a testament to private ownership's role in water resource management and climate resilience. As climate change impacts water availability and quality, the maintenance and upkeep of such reservoirs become increasingly important for sustainable water use and ecosystem health in the face of changing environmental conditions. Road Reservoir serves as a reminder of the critical role that small-scale water infrastructure plays in supporting local communities and adapting to a shifting climate landscape.

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.
