Marcel Lake Dam dam
Marcel Lake Dam
Marcel Lake Dam, located in Duvall, Washington, is a privately-owned structure used primarily for recreation. Completed in 1964, this earth dam stands at a structural height of 22 feet with a hydraulic height of 31 feet, creating a storage capacity of 750 acre-feet and a surface area of 32 acres. The dam, situated on Essency Creek, plays a crucial role in regulating water flow and providing water storage for the surrounding area.
With a fair condition assessment and a high hazard potential, Marcel Lake Dam is regulated and inspected by the Washington Department of Ecology to ensure its safety and functionality. The last inspection in July 2020 revealed that the dam is in need of regular maintenance and monitoring to mitigate potential risks. Despite its age, the dam continues to serve its purpose effectively, offering recreational opportunities and contributing to water resource management in the region.
As a key component of the water infrastructure in King County, Marcel Lake Dam plays a vital role in flood control and water supply management. Its location in the beautiful natural surroundings of Duvall makes it a popular destination for outdoor enthusiasts and nature lovers. With proper maintenance and oversight, this dam will continue to provide important benefits for the community while safeguarding against potential hazards associated with its operation.

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 Marcel Lake Dam
Where does the data for Marcel Lake 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 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.
