Summary

With a height of 11 feet and a length of 200 feet, this dam has a storage capacity of 78 acre-feet and a drainage area of 3.91 square miles. Despite being classified as having a low hazard potential, the dam is state-regulated by the DNRC, with permitting, inspection, and enforcement conducted by the state agencies.

The primary purpose of Walker #2 (Dawson) is flood risk reduction, and it stands as a crucial infrastructure in the region's water resource management. The dam has not been rated for its condition assessment, and there is limited information available regarding its emergency action plan, risk assessment, and risk management measures. While the dam has not been modified in recent years and lacks certain safety features such as spillways, it remains an essential component in mitigating flood risks in the area.

Overall, Walker #2 (Dawson) serves as a vital structure in the flood management system of Montana, providing protection to the surrounding community against potential inundation events. As climate change continues to impact water resources and extreme weather events become more frequent, the maintenance and oversight of dams like Walker #2 are crucial in ensuring the safety and resilience of the region's water infrastructure. With state regulation and monitoring in place, the dam plays a significant role in safeguarding the local ecosystem and population from the impacts of flooding.

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.
