Summary
The dam, completed in 1952, is an earth type structure standing at a height of 15 feet and holding a storage capacity of 54 acre-feet. The reservoir covers an area of 28 acres and is regulated by the Montana Department of Natural Resources and Conservation (DNRC).
The low hazard potential of Twin Lakes makes it a valuable asset for the community, providing essential water resources while also being a relatively safe structure. The dam has not been rated for its condition, but regular inspections and enforcement by state agencies ensure its continued operation and safety. The location of the reservoir along the Teton River, with a distance of 16 miles from Chouteau, adds to its importance in the region for water management and environmental conservation.
As a water resource and climate enthusiast, Twin Lakes offers a fascinating case study in sustainable water management and infrastructure development. Its multiple uses, state regulation, and low hazard potential demonstrate the importance of responsible stewardship of our water resources in the face of changing climate conditions. Twin Lakes serves as a reminder of the critical role that small-scale dams play in providing essential services while also highlighting the need for ongoing monitoring and maintenance to ensure their long-term viability.

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.
