Othello Primary Treatment Pond 1b Dam
Othello Primary Treatment Pond 1b
Othello Primary Treatment Pond 1b, located in Corfu, Washington, is a key water resource managed by the local government. This primary treatment pond plays a vital role in the state's water management system, as it is regulated, permitted, inspected, and enforced by the Washington Department of Ecology. Completed in 1982, the pond has a hydraulic height of 16 feet and a structural height of 13 feet, with a storage capacity of 200 acre-feet and a surface area of 115 acres.
With a low hazard potential and a condition assessment of "Not Rated," Othello Primary Treatment Pond 1b serves as an essential component in maintaining water quality and managing water resources in Adams County, Washington. While it does not have a spillway type or outlet gates, the pond's design as an earth dam with a rockfill core on a soil foundation ensures its stability and effectiveness in storing and treating water. Furthermore, its location near Crab Creek and offstream positioning enhances its impact on water quality in the region.
Managed by the local government and with a focus on purposes beyond flood control or irrigation, Othello Primary Treatment Pond 1b stands as a testament to the importance of water treatment and resource management in the face of climate change and increasing water demands. As climate enthusiasts and water resource stakeholders continue to monitor and assess water infrastructure like this pond, its role in preserving water quality and sustainability in the region remains crucial for future generations.

About Othello Primary Treatment Pond 1b
Where does the data for Othello Primary Treatment Pond 1b 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 below 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.
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.
