Walker #2 (Dawson) dam
Walker #2 (Dawson)
Located in Dawson, Montana, Walker #2 (Dawson) is a privately owned Earth dam designed by the USDA NRCS in 1966 for flood risk reduction along TR-Clear Creek. 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.
- 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.
- 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.
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, environmental 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.

About Walker #2 (Dawson)
Where does the data for Walker #2 (Dawson) come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
