Snohomish Wastewater Treatment Lagoon Sy dam
Snohomish Wastewater Treatment Lagoon Sy
The Snohomish Wastewater Treatment Lagoon System in Snohomish, Washington, is a vital piece of infrastructure designed to manage and treat wastewater in an environmentally responsible manner. Owned and regulated by the local government, this facility has been in operation since 1995 and plays a crucial role in protecting the health of the Snohomish River. With a low hazard potential and a focus on maintaining water quality, this facility is an essential part of the region's water resource management strategy.
Situated in Congressional District 01 and overseen by Washington's Department of Ecology, the Snohomish Wastewater Treatment Lagoon System boasts a hydraulic height of 17 feet and a storage capacity of 86 acre-feet. The facility serves a drainage area of 0.01 square miles and has a maximum discharge rate of 29 cubic feet per second. Despite its low hazard potential, this facility is subject to regular state inspections and enforcement measures to ensure its continued safe and efficient operation.
Overall, the Snohomish Wastewater Treatment Lagoon System exemplifies the importance of responsible water resource management in the face of climate change and increasing environmental pressures. By treating wastewater effectively and minimizing its impact on the surrounding ecosystem, this facility plays a crucial role in preserving the health and integrity of the Snohomish River for generations to come.
Dam data reference
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.
Plan around the weather

About Snohomish Wastewater Treatment Lagoon Sy
Where does the data for Snohomish Wastewater Treatment Lagoon Sy 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.
