Summary
Built in 1950 for fire protection, stock, and a small fish pond, this dam stands at a height of 30 feet and has a maximum storage capacity of 92 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," Crow #1 is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state inspection and enforcement protocols.
Despite its age, Crow #1 continues to serve its primary purposes effectively, providing vital water resources for fire protection and livestock. The dam's location in a sparsely populated area contributes to its low hazard potential, offering a sense of security to nearby residents and wildlife. As a significant feature in the local landscape, Crow #1 highlights the importance of maintaining and monitoring water infrastructure for both ecological and human needs in the face of changing climate conditions.
As water resource and climate enthusiasts, we recognize the critical role that dams like Crow #1 play in managing water flow, providing essential services, and adapting to a changing environment. By understanding the history, purpose, and condition of structures like Crow #1, we can better appreciate the complexities of water management and the interconnectedness of human and natural systems in the face of climate challenges.

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.
