Connell Wastewater Lagoon 1a dam
Connell Wastewater Lagoon 1a
Connell Wastewater Lagoon 1a, located in Connell, Washington, is a vital water resource managed by the local government. Designed by John Wells and completed in 2009, this Earth-type dam serves a primary purpose of wastewater management, with a hydraulic height of 22 feet and a length of 800 feet. The lagoon has a storage capacity of 17 acre-feet, with a normal storage level of 13.27 acre-feet.
This significant structure is regulated by the Washington Dept of Ecology, with state jurisdiction and enforcement in place to ensure its proper operation. Despite its satisfactory condition assessment as of 2014, the lagoon is classified as having a significant hazard potential. The dam's last inspection in 2014 revealed a satisfactory condition, and it is subject to regular inspections every five years to ensure its continued safety and functionality.
Connell Wastewater Lagoon 1a plays a crucial role in managing wastewater in Franklin County, Washington, contributing to the protection of the environment and public health in the region. As water resource and climate enthusiasts, understanding the infrastructure and operation of such facilities is essential to promoting sustainable water management practices and ensuring the resilience of our water resources in the face of changing climate conditions.
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 Connell Wastewater Lagoon 1a
Where does the data for Connell Wastewater Lagoon 1a 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.
