Summary
Built in 1948 by the USDA NRCS, this earth dam stands at a height of 20 feet and has a storage capacity of 53 acre-feet. Situated on the TR-STINKING COULEE river, Brain serves as a vital resource for the local community, offering low hazard potential and being state-regulated for inspection, enforcement, and permitting.
Managed by the DNRC, Brain dam is part of the Omaha District in Montana and falls under Congressional District 00, represented by Greg Gianforte (R). With a history of not being rated for condition assessment, Brain serves as a crucial water resource for the region, covering a drainage area of unspecified size. Despite lacking detailed information on spillways, locks, and surface area, Brain's role in providing essential water services underscores its significance for climate and water enthusiasts interested in sustainable water management practices in the region.
As an integral part of the local water infrastructure, Brain dam plays a crucial role in maintaining the environmental and social well-being of the area. With its low hazard potential and historical significance, Brain stands as a testament to the importance of proper dam management and regulation in ensuring the sustainable use of water resources for future generations. For water resource and climate enthusiasts, Brain serves as a case study in effective dam construction and management practices that can help inform future decision-making in similar projects.

Dam Data Reference
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.
