Summary
This earth dam stands at a height of 20 feet and has a storage capacity of 124 acre-feet, with a normal storage level of 63 acre-feet. The dam is situated on TR-BREED CREEK and is under the jurisdiction of the Montana Department of Natural Resources and Conservation (DNRC).
The dam has been deemed to have a significant hazard potential, although its condition has not been officially rated. Despite this, the dam has been regulated, inspected, and permitted by the state, indicating a commitment to ensuring its structural integrity and safety. While the dam has not been modified in recent years, it is essential to have emergency action plans in place and regularly updated to mitigate any potential risks associated with the dam's operation.
For water resource and climate enthusiasts, Brown (Liberty) dam serves as a vital infrastructure for agricultural irrigation in the region. Understanding its design, purpose, and regulatory oversight provides valuable insights into water management practices in Montana. As the state continues to face challenges related to water scarcity and climate change, the maintenance and monitoring of dams like Brown (Liberty) are crucial for sustainable water resource management and environmental preservation.

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.
