Summary
Completed in 1967, this dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 20 feet and a length of 300 feet, Withee #2 has a storage capacity of 62 acre-feet, providing essential water resources for the surrounding area.
Managed by the DNRC and regulated by the state of Montana, Withee #2 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its age, this dam continues to play a crucial role in water management and conservation efforts in the region. Its strategic location and design make it a valuable asset for maintaining water availability for various uses, especially during dry seasons or in case of emergencies.
With its proximity to the Omaha District and Congressional District 00, Montana, Withee #2 stands as a testament to the importance of sustainable water resource management and the critical role that dams play in supporting both environmental and human needs. As climate change continues to impact water availability, structures like Withee #2 will be vital in ensuring resilience and adaptability in the face of evolving environmental challenges.

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.
