Mud Mountain Dam dam
Mud Mountain Dam
Mud Mountain Dam, located in Buckley, Washington, is a vital flood risk reduction structure owned and operated by the US Army Corps of Engineers. Completed in 1948, the dam stands at a structural height of 425 feet and has a hydraulic height of 350 feet, with a maximum storage capacity of 106,000 acre-feet. The primary purpose of Mud Mountain Dam is flood risk reduction, with secondary benefits including recreation opportunities.
Despite being characterized as having a high hazard potential, Mud Mountain Dam is well-maintained and monitored by the US Army Corps of Engineers to ensure its structural integrity and effectiveness. The dam has never experienced spillway use, but in the event of a failure scenario, the downstream consequences could involve deadly flooding and economic damages. To mitigate these risks, the Corps has an Emergency Action Plan in place and conducts regular inspections, maintenance, and repairs. Additionally, the Corps collaborates with local emergency managers and stakeholders to update the Emergency Action Plan and enhance risk management measures.
In conclusion, the US Army Corps of Engineers is dedicated to reducing risks to life safety and property associated with Mud Mountain Dam. Through ongoing monitoring, inspections, and proactive measures, the Corps aims to maintain the dam's functionality during extreme events and prevent catastrophic flooding downstream. Mud Mountain Dam serves as a critical infrastructure for flood risk reduction in the region, showcasing the importance of effective water resource management and climate resilience efforts.

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 Mud Mountain Dam
Where does the data for Mud Mountain Dam 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 High 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.
