N Marysville Regional Stormwater Pond No. 2 dam
N Marysville Regional Stormwater Pond No. 2
N Marysville Regional Stormwater Pond No. 2, located in Marysville, Washington, is a vital structure designed by Laura Ruppert to address flood risk reduction in the area. Managed by the Washington Department of Ecology, this stormwater pond is state-regulated and regularly inspected to ensure its effectiveness. Completed in 2015, this earth dam structure has a hydraulic height of 7 feet and a storage capacity of 99 acre-feet, providing essential drainage for a 0.27 square mile area.
With a surface area of 6.8 acres and a normal storage capacity of 14 acre-feet, this stormwater pond plays a crucial role in managing water flow from the Quilceda Creek. Despite its high hazard potential, the structure is deemed to be in satisfactory condition as of the last inspection in July 2021. The Emergency Action Plan (EAP) for the pond, last revised in 2017, ensures that necessary guidelines are in place for any potential emergencies, further highlighting the commitment to effective risk management measures.
Water resource and climate enthusiasts will appreciate the strategic design and functionality of N Marysville Regional Stormwater Pond No. 2, which serves as a key component in the flood risk reduction efforts in Snohomish County, Washington. As a local government-owned structure, this pond exemplifies the collaborative efforts between state agencies and designers to create sustainable solutions for water management. Its successful operation and maintenance underscore the importance of proactive measures in safeguarding communities against potential flooding incidents.
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 N Marysville Regional Stormwater Pond No. 2
Where does the data for N Marysville Regional Stormwater Pond No. 2 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.
