Summary
The reservoir has a dam height of 25 feet and a storage capacity of 307 acre-feet, with a normal storage level of 169 acre-feet. The reservoir is situated along the TR-FARGO COULEE, with a drainage area of 0.31 square miles and a maximum discharge capacity of 228 cubic feet per second.
Despite being classified as having a low hazard potential and a moderate risk assessment rating, Fink Reservoir is state-regulated and inspected for safety and compliance by the Montana Department of Natural Resources and Conservation (DNRC). The reservoir's spillway, which is uncontrolled and 15 feet wide, helps manage water levels during high flow events. The site is located within the jurisdiction of the Omaha District of the US Army Corps of Engineers, with Congressional oversight from Representative Greg Gianforte.
Water resource and climate enthusiasts can appreciate Fink Reservoir as a vital component of water management in the region, providing valuable water storage for various purposes while also serving as a fire protection resource. The reservoir's construction and ongoing maintenance demonstrate a commitment to sustainable water infrastructure, with state oversight ensuring safety and regulatory compliance. With its tranquil setting and strategic location within the natural landscape, Fink Reservoir is a noteworthy example of responsible water resource management in Montana.

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.
