Watr monitoring station in the McKenzie River
Enhanced Monitoring Key to a Healthy Watershed 02/11/2021

On the heels of the Holiday Farm Fire, we quickly got to work with partner agencies and research organizations to identify post-fire threats to water quality in the McKenzie River. Additional water quality sensors have been placed in the main stem of the river, as well as in several creeks and tributaries. The widespread damage from the fire will likely threaten water quality for years, and these sensors are essential tools to the on-going recovery effort.

Real-time monitoring, especially during major storm events, provides important data about the location, amount, and types of contaminants flushed into the river. This information can act as an early warning system to adjust treatment practices at EWEB's filtration plant downstream and help prioritize watershed restoration activities.

During the past few heavy rain events, monitors detected turbidity levels that were significantly higher than typical for the McKenzie River—a result of sediment from the surrounding land washing into the river. Analytical results from the expanded real-time monitoring network also showed an increase in nutrients, metals, and organic compounds coming from the burned and eroded landscape above the river. 

Fortunately, these impacts seem to be short-lived and the water quality issues experienced so far are well within the capacity of EWEB's treatment plant to handle. Read more about your drinking water quality.

Protecting water quality requires a "source to tap" mentality, not simply relying on treatment measures to mitigate problems. The Holiday Farm Fire disaster presents an opportunity to rebuild smarter and strategically scale up source protection activities with an eye towards a more resilient watershed.

EWEB and our partners are looking for opportunities to implement large-scale floodplain restoration in key areas to mitigate flooding, erosion, and water quality impacts from severely burned landscapes.  We also hope to work with area residents to replant some 100 acres of high priority riparian areas this winter.
