Stark Dam Reservoir Report

Last Updated: December 5, 2025

Stark Dam, located in Wibaux, Montana, along TR-Beaver Creek, was completed in 1945 with a primary purpose of providing fire protection, stock, and a small fish pond.

Summary

This earth dam stands at 20 feet in height and spans a length of 300 feet, with a storage capacity of 264 acre-feet. Owned privately, Stark Dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with state jurisdiction, permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.

Despite its low hazard potential and current "Not Rated" condition assessment, Stark Dam plays a crucial role in water resource management in Fallon County, Montana. With a normal storage capacity of 33 acre-feet, the dam serves as a vital source of water for fire protection and livestock use in the area. Its strategic location and design make it a valuable asset for local communities and wildlife, contributing to the overall ecosystem health and sustainability in the region.

As climate change continues to impact water resources globally, Stark Dam stands as a testament to the importance of responsible water management practices. With its historical significance and functional purpose, this earth dam serves as a symbol of resilience and adaptability in the face of evolving environmental challenges. Enthusiasts and stakeholders alike can appreciate Stark Dam not only for its practical benefits but also for its contribution to the broader conversation on water conservation and climate resilience.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
