Summary
Built in 1968 for purposes of fire protection, stock, and small fish pond, this earth dam stands at a height of 25 feet with a hydraulic height of 22 feet. The dam has a storage capacity of 107 acre-feet, with a normal storage level of 69 acre-feet.
With a low hazard potential and a moderate risk assessment rating, Big Timber #24 has not been assessed for its condition but is currently not rated. The spillway of the dam is uncontrolled with a width of 100 feet, and it is regulated by the Montana Department of Natural Resources and Conservation. Despite lacking detailed information on inspections and emergency preparedness, this dam serves as a crucial resource for water management and conservation in the region.
Enthusiasts of water resources and climate in the area can appreciate the role of Big Timber #24 in providing essential services such as fire protection and water storage. Its strategic location in Rosebud County, Montana, highlights its significance in the local ecosystem and underscores the importance of monitoring and maintaining the dam to ensure its continued functionality and safety for the community.

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.
