Summary
Completed in 1930 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a dam height of 20 feet and a storage capacity of 216 acre-feet, Bramlette plays a crucial role in water resource management in the region.
Despite being classified as a low hazard potential structure with a moderate risk assessment rating, Bramlette is regulated and permitted by the Montana Department of Natural Resources and Conservation (DNRC). The dam has a spillway width of 30 feet and a maximum discharge capacity of 700 cubic feet per second, ensuring the efficient management of excess water during periods of high flow. With a drainage area of 12.5 square miles, Bramlette provides essential water storage and flood protection benefits to the local community.
Maintaining Bramlette's structural integrity and regulatory compliance is essential for ensuring its continued functionality and safety. While the dam's condition assessment is currently listed as "Not Rated," regular inspections, emergency action plans, and risk management measures are crucial for mitigating potential hazards and ensuring the long-term sustainability of this vital water resource infrastructure in Chouteau County, Montana.

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.
