Summary
Constructed in 1960, this earth dam stands at 18 feet high and has a storage capacity of 128 acre-feet. With a low hazard potential and moderate risk assessment, the reservoir serves as a vital resource for the surrounding area.
The reservoir is situated on TR-SNOW CREEK and is regulated by the State of Montana with inspections and enforcement carried out by the DNRC. With a maximum discharge of 500 cubic feet per second and an uncontrolled spillway, the dam plays a critical role in water management and flood control in the region. Despite not being rated for its condition, the reservoir continues to provide essential services to the community.
While Hauso Reservoir #2 has not been assessed for its condition or emergency action plan readiness, its strategic location and design make it a key asset for fire protection and livestock management. With a history dating back to the 1960s, this reservoir remains a valuable resource for water resource and climate enthusiasts in Montana, contributing to the overall resilience of the area's water infrastructure.

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.
