Summary
This gravity dam stands at a structural height of 17 feet with a hydraulic height of 10 feet, serving as a crucial water resource for the Beaver Creek/Milk River system. With a storage capacity of 361.95 acre-feet and a surface area of 127 acres, the dam plays a vital role in regulating water flow and providing essential resources to the surrounding area.
Owned, funded, designed, and regulated by the Bureau of Land Management, this retention dam has a low hazard potential with a condition assessment of "Not Rated." The dam has not been inspected since August 2016, with an inspection frequency of 5 years. Despite its age, the dam continues to serve its intended purposes effectively, showcasing the importance of proper maintenance and oversight of water infrastructure in mitigating potential risks and ensuring water resource sustainability. As a key component of the local water management system, Pr-161 Retention Dam remains a significant asset for the community and the environment, highlighting the critical role of dams in promoting water conservation and climate resilience in the region.

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.
