Kennewick No 2 Aerated Wastewater Lagoon dam
Kennewick No 2 Aerated Wastewater Lagoon
Kennewick No 2 Aerated Wastewater Lagoon in Kennewick, Washington, is a vital facility owned and regulated by the local government to manage wastewater effectively. Built in 1975 by JUB Engineers, this lagoon is designed to aerate wastewater and has a storage capacity of 153 acre-feet. Situated offstream from the Columbia River, it serves a drainage area of 0.02 square miles and covers an area of 8.7 acres.
The lagoon stands at a hydraulic height of 24 feet, with a high hazard potential and fair condition assessment. It is regularly inspected by the Washington Department of Ecology, emphasizing its importance in maintaining water quality and environmental safety. Despite its critical role in wastewater management, the lagoon does not have a spillway or outlet gates, highlighting its unique design and purpose in the region.
Located in Benton County, Washington, the Kennewick No 2 Aerated Wastewater Lagoon plays a crucial role in the local water resource management system. With its state jurisdiction, permitting, and enforcement, it ensures the effective treatment of wastewater while complying with regulatory standards. As a key infrastructure for the region, the lagoon signifies the commitment to sustainable water management practices and environmental protection in Kennewick.
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 Kennewick No 2 Aerated Wastewater Lagoon
Where does the data for Kennewick No 2 Aerated Wastewater 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.
