Summary
This reservoir, with a primary purpose of water supply, is owned and regulated by the State of Montana, specifically by the Department of Natural Resources and Conservation (DNRC). The dam, classified as an Earth type, stands at a height of 30.1 feet and has a maximum storage capacity of 64.32 acre-feet, providing essential water storage for the region.
With a significant hazard potential, Deadmans Basin Water Supply Canal Storage Reservoir #5 plays a crucial role in water management and supply for Wheatland County, Montana. The reservoir has a normal storage capacity of 46.2 acre-feet and covers a surface area of 8.78 acres. While the condition assessment is currently marked as "Not Rated," the state conducts regular inspections, enforcement, and permitting for this structure to ensure its safety and functionality. In the case of emergencies, the reservoir's Emergency Action Plan (EAP) readiness and risk management measures are yet to be assessed, highlighting the importance of continuous monitoring and preparedness for potential risks and disasters.

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.
