N Marysville Regional Stormwater Pond dam
N Marysville Regional Stormwater Pond
The N Marysville Regional Stormwater Pond in Snohomish County, Washington, is a vital infrastructure managed by the local government to reduce flood risks in the area. Designed by OTAK Inc. and completed in 2004, this earth dam structure serves the primary purpose of flood risk reduction for the surrounding community. With a hydraulic height of 11.4 feet and a structural height of 10.8 feet, this stormwater pond plays a crucial role in managing stormwater runoff and protecting the nearby Quilceda Creek.
Covering a surface area of 5.8 acres and having a drainage area of 0.13 acres, this stormwater pond has a storage capacity of 36 acre-feet, offering significant flood mitigation benefits for the region. The facility is state-regulated and inspected, ensuring its operational efficiency and compliance with environmental standards. Despite being classified as having a high hazard potential, the N Marysville Regional Stormwater Pond is currently deemed to be in satisfactory condition, as assessed in August 2021.
Located in Marysville, Washington, this stormwater pond is a crucial component of the region's water resource management infrastructure. With a history of successful flood risk reduction and effective operation, this facility stands as a testament to the importance of sustainable water management practices in combating the challenges posed by climate change and urban development.
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 N Marysville Regional Stormwater Pond
Where does the data for N Marysville Regional Stormwater Pond 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.
