Portland, Ore. -The Oregon Health Authority has lifted the health advisory issued Aug. 19 for the Willamette River’s Ross Island Lagoon. Ross Island Lagoon is located about one mile south of downtown Portland in Multnomah County.
Water monitoring has confirmed that the number of blue-green algae cells as well as levels of associated toxins are below guideline values for human exposure.
Oregon health officials advise recreational visitors to always be alert to signs of algae blooms in Oregon waters. People and their pets should avoid areas where the water is foamy, scummy, thick like paint, pea-green, blue-green or brownish red in color, if a thick mat of blue-green algae is visible in the water, or bright green cells are suspended in the water column.
If you observe these signs in the water, you are encouraged to avoid activities that cause you to swallow water or inhale droplets, such as swimming or high-speed water activities.
