Deer Park Waste Water Storage Lagoon dam
Deer Park Waste Water Storage Lagoon
Deer Park Waste Water Storage Lagoon, located within the city limits of Deer Park, Washington, is a vital water resource managed by the local government. Built in 1985, this Earth-type dam stands at a hydraulic height of 26 feet, with a structural height of 15 feet and a length of 2183 feet. The lagoon has a maximum storage capacity of 205 acre-feet, with a normal storage level of 176 acre-feet, serving a drainage area of 0.02 square miles.
The lagoon is regulated, permitted, inspected, and enforced by the Washington Department of Ecology, ensuring compliance with state guidelines. The last inspection in July 2019 rated the dam's condition as fair, with a high hazard potential. While the dam does not have an Emergency Action Plan (EAP) in place, it undergoes inspections every 5 years to maintain safety standards. Despite its hazard potential, the lagoon plays a crucial role in waste water management and contributes to the overall water resource infrastructure in the area.
Deer Park Waste Water Storage Lagoon serves as a key component of the water management system in Spokane County, Washington, providing a critical function in storing and regulating waste water discharge. With its capacity to hold 205 acre-feet of water and a surface area of 176 acres, the lagoon plays a significant role in safeguarding the local environment and waterways. As climate change continues to impact water resources, the maintenance and upkeep of infrastructure like the Deer Park Lagoon are essential to ensure the sustainability and resilience of the region's water supply.

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 Deer Park Waste Water Storage Lagoon
Where does the data for Deer Park Waste Water Storage Lagoon 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.
