Everett Reservoir No 4 dam
Everett Reservoir No 4
Everett Reservoir No 4, located in Everett, Washington, is a critical water supply infrastructure managed by the local government. Completed in 1952, this Earth dam stands at a hydraulic height of 24 feet and has a storage capacity of 74 acre-feet. The reservoir serves the primary purpose of water supply and is regulated by the Washington Department of Ecology, ensuring proper inspection and enforcement measures are in place to maintain its structural integrity.
With a surface area of 2.8 acres and draining a small area of 0.01 square miles, Everett Reservoir No 4 plays a vital role in providing water to the residents of Snohomish County. Despite its high hazard potential, the dam's condition assessment remains satisfactory as of the last inspection in June 2016. Emergency action plans are in place to address any potential risks, with the last revision dated June 2017, showcasing a commitment to proactive risk management.
The reservoir's location near Tr-Possession Sound highlights its strategic importance in the region's water resource management. As climate change continues to impact water availability and quality, infrastructure like Everett Reservoir No 4 becomes increasingly crucial for ensuring a stable and reliable water supply for the community. With a strong regulatory framework in place and regular inspections, this reservoir stands as a testament to responsible water resource management in the face of evolving environmental challenges.
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.

About Everett Reservoir No 4
Where does the data for Everett Reservoir No 4 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.
