Summary
With a height of 20 feet and a storage capacity of 60 acre-feet, this earth dam serves primarily for irrigation purposes in the region. Managed by the Montana Department of Natural Resources and Conservation (DNRC), the dam is regulated, inspected, and enforced by the state to ensure its safety and functionality.
Despite being classified as a low-hazard structure with a condition assessment of "Not Rated," Gray #2 plays a crucial role in supporting agricultural activities in the area. The dam is situated in Congressional District 00, represented by Greg Gianforte, and falls under the jurisdiction of the Omaha District. While the dam has not been modified in recent years and lacks certain key infrastructure details, it remains a vital component of the local water resource management system.
As water resource and climate enthusiasts, it is important to recognize the significance of structures like Gray #2 in sustaining agricultural production and water supply in rural communities. By understanding the regulatory framework, ownership, and purpose of dams like Gray #2, we can better appreciate the interconnectedness of water infrastructure and the environment, and work towards ensuring the safety and sustainability of these essential resources for future generations.

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.
