Connell Wastewater Lagoon 4 dam
Connell Wastewater Lagoon 4
Connell Wastewater Lagoon 4, located in Connell, Washington, is a vital infrastructure managed by the local government. This lagoon, designed by John Wells, serves as a key component in the state's regulatory framework for water resource management. With a capacity of 109 acre-feet and a surface area of 10.1 acres, it plays a crucial role in treating wastewater and ensuring environmental sustainability in the region.
Constructed in 2009, Connell Wastewater Lagoon 4 is an earth dam with a height of 10 feet and a length of 1450 feet. It has a significant hazard potential but has been assessed to be in satisfactory condition. The lagoon undergoes regular inspections, with the last one conducted in April 2014. It is equipped with emergency action plans to mitigate any risks and ensure the safety of the surrounding community in case of unforeseen events.
Situated in Franklin County, Washington, this wastewater lagoon is an essential component of the local water infrastructure. Its close monitoring, inspection, and maintenance demonstrate the commitment to safeguarding water resources and the environment. As climate change continues to impact water supplies and infrastructure, the sustainable management of facilities like Connell Wastewater Lagoon 4 is crucial for ensuring water security and resilience in the face of evolving challenges.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Connell Wastewater Lagoon 4
Where does the data for Connell Wastewater Lagoon 4 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 Significant 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.
