Summary
Built in 1940 by the USDA NRCS, this earth dam stands at a height of 20 feet and spans 175 feet in length, providing a storage capacity of 219 acre-feet. Situated on Cottonwood Creek N Fork, Gray 13 serves as a vital resource for water management and conservation in the region.
Despite its low hazard potential, the condition assessment of Gray 13 is currently marked as "Not Available," with no recent inspection date provided. The emergency action plan status, inundation maps, risk assessment, and risk management measures are also listed as unavailable. With its importance in fire protection and water storage, it is crucial to ensure regular inspection and maintenance of Gray 13 to uphold its functionality and safety for both agricultural and environmental purposes.
As a key component in the water infrastructure of Rosebud, Montana, Gray 13 warrants attention from water resource and climate enthusiasts to advocate for proper monitoring and maintenance practices. With its historical significance and essential role in water management, this structure serves as a reminder of the importance of sustainable water resource management 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.
