Boeing Creek M1 Detention Dam dam
Boeing Creek M1 Detention Dam
Boeing Creek M1 Detention Dam, located within Seattle's city limits, serves as a vital flood risk reduction structure along Boeing Creek. Built in 1983, this earth dam stands at a hydraulic height of 40 feet and a structural height of 27 feet, with a length of 160 feet. The dam's primary purpose is flood risk reduction, contributing to the protection of the surrounding area from potential flooding events.
Managed by the Washington Department of Ecology, the dam is state-regulated and inspected regularly to ensure its satisfactory condition and high hazard potential. With a storage capacity of 12.5 acre-feet and a maximum discharge capability of 1200 cubic feet per second, the dam plays a crucial role in managing water levels and reducing flood risks in the region. Despite its solid structural assessment, emergency action plans are in place to address any unforeseen events and ensure the safety of the community.
Boeing Creek M1 Detention Dam stands as a testament to effective water resource management and climate resilience efforts in King County, Washington. With its strategic location and robust design, the dam continues to provide essential flood protection to the area, highlighting the importance of proactive infrastructure investments in mitigating the impacts of changing climate patterns on water resources and communities.

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 Boeing Creek M1 Detention Dam
Where does the data for Boeing Creek M1 Detention 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.
