Metropolitan Sludge Ponds (Lagoon) dam
Metropolitan Sludge Ponds (Lagoon)
Metropolitan Sludge Ponds (Lagoon) in Santa Clara, Lane County, Oregon, is a vital water resource managed by the local government with state jurisdiction and regulation. Built in 1987, this earth dam structure stands at a height of 15 feet and serves a primary purpose of waste management, offering a storage capacity of 160 acre-feet for wastewater treatment. The lagoon covers a surface area of 25 acres and is equipped with a slide (sluice gate) outlet gate for controlled discharge.
Despite its low hazard potential, Metropolitan Sludge Ponds play a crucial role in managing wastewater in the region, ensuring environmental safety and compliance with state permitting and inspection requirements. Located within the Portland District, the facility is not only essential for waste treatment but also demonstrates a commitment to sustainable water management practices. With regular inspections and a designated emergency action plan, the lagoon is well-prepared to handle any unforeseen events and ensure the safety of surrounding communities.
As a key component of the local water infrastructure, Metropolitan Sludge Ponds exemplify the importance of responsible water resource management in mitigating climate impacts and preserving water quality. With a focus on waste treatment and environmental protection, this facility showcases the intersection of water resources and climate resilience, highlighting the crucial role that such structures play in maintaining the health and sustainability of our ecosystems.

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 Metropolitan Sludge Ponds (Lagoon)
Where does the data for Metropolitan Sludge Ponds (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 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.
