Summary
Constructed in 1950, this dam stands at a height of 12 feet and has a storage capacity of 84 acre-feet, primarily serving the purposes of fire protection, stock, and small fish pond. Situated on Sagebrush Creek, this low hazard potential dam is regulated by the Department of Natural Resources and Conservation (DNRC) in Montana.
The structure's primary function is to provide essential water resources for fire protection and livestock in the area. As a privately owned dam, it is subject to state regulation and inspection, ensuring its safety and compliance with state standards. Despite its low hazard potential, the condition assessment of Hastetter #1 is currently not rated, indicating a need for further evaluation and monitoring to ensure its continued functionality.
For water resource and climate enthusiasts, Hastetter #1 presents an intriguing case study of a privately owned dam in Montana. With its historical significance dating back to 1950, this earth dam on Sagebrush Creek serves multiple purposes while being closely monitored by state regulatory agencies. Understanding the management and maintenance of such structures is crucial for ensuring the sustainable use of water resources in the region and mitigating potential risks associated with dam failure.

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.
