Summary
Completed in 1945, the dam serves multiple purposes including fire protection, stock, and a small fish pond. With a dam height of 20 feet and a storage capacity of 183 acre-feet, the structure has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.
Although the dam is not federally owned, it is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and subject to state jurisdiction, permitting, inspection, and enforcement. The primary source agency for Brady #4 is the state of Montana, and it falls under the Congressional District 00 represented by Greg Gianforte. While specific details on the dam's inspection frequency, emergency action plan, and risk management measures are not provided in the data, it is clear that the structure plays a vital role in water resource management for the local area.
For water resource and climate enthusiasts, Brady #4 represents a key infrastructure project in Montana that contributes to fire protection, livestock needs, and ecological diversity through its small fish pond. As a privately owned earth dam, it showcases the importance of state regulation and oversight in ensuring the safety and functionality of water storage structures. With its historic completion date and ongoing relevance in the region, Brady #4 serves as a reminder of the interconnectedness of water resources and the need for sustainable management practices in the face of changing climate 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.
