Summary
Built in 1955, this earth dam stands at a height of 28 feet and spans 600 feet in length, with a storage capacity of 296 acre-feet. Situated in a picturesque setting, Sportsman offers a tranquil environment for outdoor enthusiasts to engage in various water activities such as fishing, boating, and bird-watching.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Sportsman is classified as having significant hazard potential due to its size and location. While the dam's condition is currently not rated, regular inspections and enforcement measures are in place to ensure its structural integrity and safety for visitors. Despite its age, Sportsman continues to provide a popular recreational destination for locals and tourists alike, offering a peaceful escape in the heart of nature.
For water resource and climate enthusiasts, Sportsman serves as a prime example of how human-made structures can harmoniously coexist with the environment, providing both recreational opportunities and essential water management functions. As efforts continue to maintain and monitor its condition, Sportsman remains a testament to the importance of responsible stewardship in preserving our natural resources for future generations to enjoy.

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.
