Summary
Completed in 1946, this earth dam stands at a height of 15 feet and boasts a storage capacity of 167 acre-feet. With a primary purpose of flood risk reduction, Hasland #2 is under state regulation by the Montana Department of Natural Resources and Conservation (DNRC), ensuring that it is regularly inspected and maintained to meet safety standards.
Although Hasland #2 has a low hazard potential, its condition assessment has not been rated, highlighting the need for ongoing monitoring and maintenance. Despite its age, this dam continues to serve its purpose effectively, showcasing the enduring engineering behind its design and construction. As a privately owned structure, it plays a crucial role in safeguarding the surrounding area from potential flooding events, demonstrating the importance of responsible water resource management in the face of changing climate conditions.
As water resource and climate enthusiasts continue to study and appreciate the significance of dams like Hasland #2, their role in mitigating flood risks and protecting communities becomes increasingly clear. With state oversight and a commitment to safety, these structures stand as testaments to human ingenuity in adapting to and managing the challenges posed by water resources and climate change.

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.
