Summary
This gravity-type dam stands at a structural height of 15 feet and has a hydraulic height of 11 feet, with a length of 571 feet. The dam has a storage capacity of 756.56 acre-feet and covers a surface area of 51.89 acres, serving as a crucial infrastructure for managing water resources in the region.
Owned and funded by the Bureau of Land Management, Vr-72 Dam plays a vital role in mitigating flood risks and ensuring water security in Valley County, Montana. Despite its low hazard potential, the dam undergoes regular inspections every five years to assess its condition and readiness for emergencies. While the dam's condition is currently not rated, it remains a key asset for maintaining the safety and sustainability of the surrounding area's water supply, highlighting the importance of effective dam management practices in the face of climate change and increasing water resource challenges.
As a significant piece of infrastructure in the region, Vr-72 Dam's construction, ownership, and operation by the Bureau of Land Management demonstrate the commitment to ensuring the resilience of water resources and infrastructure against potential hazards. The dam's contribution to flood risk reduction and water storage underscores its critical role in safeguarding communities and ecosystems along Rock Creek and the Milk River, showcasing the essential intersection of water resource management and climate resilience in the face of changing environmental conditions.

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.
