Panther Lk First Avenue Bas Detent Pond dam
Panther Lk First Avenue Bas Detent Pond
Panther Lake First Avenue Basin Detention Pond, also known as Quadrant - Panther Lake Pond, is a privately owned water resource structure located in Federal Way, Washington. Managed by the Washington Department of Ecology, this facility plays a crucial role in flood risk reduction along the Hylebos Creek offstream. Completed in 2000, the earth dam structure has a hydraulic height of 9 feet and a storage capacity of 18 acre-feet, providing essential protection for the surrounding area.
With a hazard potential rated as high, regular inspections and enforcement ensure the dam's satisfactory condition and overall safety. The pond's primary purpose of flood risk reduction underscores its vital role in protecting the community from potential inundation. Despite being a privately owned facility, it is regulated, permitted, and inspected by the state regulatory agency, reflecting a commitment to maintaining the integrity and functionality of the structure for the benefit of water resource and climate enthusiasts in the region.
Situated in King County, Washington, the Panther Lake First Avenue Basin Detention Pond serves as a key component in the local flood risk management strategy. Its strategic location, design, and capacity contribute to the overall resilience of the area against potential flooding events. As a testament to its importance, the facility meets state jurisdiction and regulatory standards, ensuring that it continues to fulfill its critical role in safeguarding the community and environment from the impacts of water-related hazards. For water resource and climate enthusiasts, this facility represents a tangible example of effective infrastructure that serves both practical and environmental purposes in the region.
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 Panther Lk First Avenue Bas Detent Pond
Where does the data for Panther Lk First Avenue Bas Detent 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.
