Oak Harbor Wastewater Lagoon Nw Cell dam
Oak Harbor Wastewater Lagoon Nw Cell
The Oak Harbor Wastewater Lagoon Nw Cell in Washington state is a crucial piece of infrastructure owned by the local government and regulated by the Washington Dept of Ecology. This lagoon serves a primary purpose of wastewater treatment and is located in Island County, with a drainage area of 0.01 square miles. Completed in 1990, this earth dam structure has a hydraulic height of 8 feet and a length of 2700 feet, providing a storage capacity of 60 acre-feet.
Despite its low hazard potential, the Oak Harbor Wastewater Lagoon Nw Cell plays a vital role in managing wastewater and protecting water resources in the area. With a normal storage capacity of 50 acre-feet and a surface area of 8.2 acres, this lagoon helps prevent pollution and maintain the health of the Tr-Crescent Harbor-Offstream water body. The structural integrity of the dam is not currently rated, but regular inspections, enforcement, and permitting ensure that it remains in compliance with state regulations.
Overall, the Oak Harbor Wastewater Lagoon Nw Cell is a key component of the local water infrastructure, providing essential wastewater treatment services while minimizing environmental impact. With its low hazard potential and strong regulatory oversight, this earth dam structure serves as a model for effective water resource management in the region. Climate enthusiasts and water resource professionals alike can appreciate the importance of this facility in maintaining the health and sustainability of the surrounding ecosystem.
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 Oak Harbor Wastewater Lagoon Nw Cell
Where does the data for Oak Harbor Wastewater Lagoon Nw Cell 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 Low 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.
