Mill Pond Stormwater Detention Dam dam
Mill Pond Stormwater Detention Dam
The Mill Pond Stormwater Detention Dam in Auburn, Washington, stands as a crucial infrastructure designed for flood risk reduction. Completed in 1994, this earth dam with a stone core serves its primary purpose of safeguarding the local community from potential flooding events. With a hydraulic height of 10 feet and the capacity to store up to 16 acre-feet of water, this offstream structure plays a significant role in managing stormwater runoff and protecting downstream areas.
Located in King County, Washington, the Mill Pond Dam is regulated by the Washington Department of Ecology and undergoes regular inspections to ensure its structural integrity. Despite being assessed as in fair condition in 2015, the dam's hazard potential is classified as high, highlighting the importance of ongoing maintenance and monitoring efforts. The dam's emergency action plan was last revised in 2017, underscoring the commitment to preparedness and risk management in the face of potential emergencies.
As a vital component of the local flood control system, the Mill Pond Stormwater Detention Dam plays a critical role in mitigating flood risks in the region. With its strategic location and design, this dam stands as a testament to effective water resource management and climate resilience efforts in the state of Washington. By fulfilling its designated purpose and adhering to regulatory standards, the Mill Pond Dam serves as a valuable asset in safeguarding the community and preserving the surrounding environment for generations to come.
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 Mill Pond Stormwater Detention Dam
Where does the data for Mill Pond 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 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.
