60th Street Stormwater Detention Dam dam
60th Street Stormwater Detention Dam
The 60th Street Stormwater Detention Dam, located within Everett City Limits in Snohomish, Washington, serves as a crucial flood risk reduction structure in the area. Completed in 1988, this earth dam with a structural height of 76 feet and a hydraulic height of 104 feet plays a vital role in managing stormwater and protecting the surrounding community from potential flooding events. With a normal storage capacity of 10 acre-feet and a maximum storage capacity of 307 acre-feet, this dam helps regulate the flow of water and mitigate potential hazards during heavy rainfall.
Managed by the Washington Dept of Ecology, the 60th Street Stormwater Detention Dam undergoes regular inspections to ensure its structural integrity and effectiveness in flood risk reduction. The dam is classified as having a significant hazard potential, yet its condition was assessed as satisfactory during the last inspection in August 2015. With the primary purpose of flood risk reduction, this essential infrastructure demonstrates the commitment of local government in Snohomish, Washington, to protect its residents and manage water resources effectively.
For water resource and climate enthusiasts, the 60th Street Stormwater Detention Dam serves as a fascinating example of engineering excellence in managing stormwater and reducing flood risks. With a history dating back to 1988, this earth dam continues to play a vital role in safeguarding the community within Everett City Limits. As a state-regulated structure with a significant hazard potential, the dam's satisfactory condition assessment and regular inspections highlight the dedication of local authorities to ensure the safety and resilience of the surrounding area in the face of changing weather patterns and increased water flow.
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 60th Street Stormwater Detention Dam
Where does the data for 60th Street Stormwater 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 Significant 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.
