Summary
This reservoir has a dam height of 16 feet and a storage capacity of 70 acre-feet, with a normal storage level of 30 acre-feet. The reservoir is situated on Halfdahl Coulee and is regulated by the Montana Department of Natural Resources and Conservation (DNRC).
The Fisher Reservoir has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam is not under the ownership or funding of any federal agency and has not been modified since its completion in 1960. Despite the lack of recent inspection and assessment data, the reservoir continues to serve its intended purposes and provides essential water resources for fire protection, livestock, and recreational fishing in the area.
While Fisher Reservoir may not be as large or well-known as other water bodies in Montana, its significance lies in its ability to support local water needs and provide a sustainable resource for the surrounding community. Climate enthusiasts and water resource advocates can appreciate the importance of small-scale reservoirs like Fisher in ensuring water security and resilience in the face of changing environmental conditions.

Dam Data Reference
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.
