Summary
This private earth dam, completed in 1964, stands at a height of 15 feet with a length of 250 feet, providing a storage capacity of 138 acre-feet. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is classified as having a low hazard potential.
Situated on TR-Blood Creek, the N Barnett #1 dam plays a crucial role in the local water resource management system, providing essential water for firefighting efforts, livestock, and recreational fishing. Despite not being rated for condition assessment, the dam has been inspected by state authorities for safety and regulatory compliance. With a history of serving the community for over half a century, the N Barnett #1 dam continues to support the diverse water needs of the region.
Water resource and climate enthusiasts will appreciate the role that the N Barnett #1 dam plays in sustaining water availability in the arid landscape of Montana. As a key infrastructure for fire protection and agricultural activities, this dam showcases the importance of effective water management in mitigating the impacts of a changing climate. With its regulated status and low hazard potential, the N Barnett #1 dam stands as a testament to the collaborative efforts between private owners and state agencies in ensuring the safety and sustainability of water resources in the region.

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.
