Summary
Completed in 1960, this earth dam stands at a height of 38 feet and has a storage capacity of 91 acre-feet, with a normal storage level of 79 acre-feet. Despite its relatively small size, the dam poses a high hazard potential and is classified as having a moderate risk level.
Owned privately and regulated by the Montana Department of Natural Resources and Conservation (DNRC), Davis Creek Dam has not been rated for its current condition as of the last inspection in 2016. With an uncontrolled spillway and a spillway width of 10 feet, the dam is designed to manage the flow of water effectively. Although no specific risk management measures are outlined, the dam is inspected every 5 years to ensure its continued safety and functionality.
Situated within the picturesque Powell County, this dam is a vital component of the local water resource infrastructure. With its strategic location and purposeful design, Davis Creek Dam stands as a testament to the importance of effective water management in the region, highlighting the essential role it plays in supporting agricultural activities and maintaining the overall environmental balance.

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.
