Summary

Owned by a private entity, this earth-type dam spans 250 feet in length and reaches a height of 43 feet, with a hydraulic height of 38 feet. With a storage capacity of 110 acre-feet, the dam serves the surrounding area by providing essential water resources for agricultural activities.

Managed by the Montana Department of Natural Resources and Conservation (DNRC), the Peet Creek Dam has been deemed to have significant hazard potential. While its condition has not been rated, the dam is subject to state regulation, inspection, and enforcement to ensure its safety and functionality. Despite lacking specific details on its construction year and maintenance history, the dam's critical role in sustaining local irrigation needs underscores the importance of ongoing monitoring and risk management measures.

Peet Creek Dam's presence along the Peet Creek river underscores the vital role it plays in water resource management in Beaverhead County. As climate change continues to impact water availability and distribution, the dam's ability to store and regulate water flow becomes increasingly essential. With its location in a congressional district represented by Greg Gianforte, the dam's significance extends beyond its immediate surroundings, highlighting the interconnectedness of water resources and climate resilience efforts in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
