Summary
Designed by Brian Kimsey & Carter Engineering Consultants, this dam serves the purpose of providing water storage for the surrounding area. With a surface area of 72 acres, the dam has a low hazard potential and a moderate risk assessment rating.
Although the dam is uncontrolled with an uncontrolled spillway, it is inspected every 5 years to ensure its structural integrity. The condition of the dam is currently not rated, but it meets the guidelines for emergency action plans. While the risk management measures and risk characterization summary are not provided in the data, it is clear that this dam plays a crucial role in water resource management in the region.
For water resource and climate enthusiasts, Big Sky - West Tract Lake Dam represents a vital infrastructure project that facilitates water storage, particularly in times of need. With its moderate risk assessment and low hazard potential, the dam underscores the importance of proper maintenance and monitoring to ensure the safety and efficiency of water resource management systems.

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.
