Walterville Pond Health advisory
A health advisory is being issued today due to high levels of blue-green algae in Walterville Pond, located off Hwy. 126.
Walterville Pond is adjacent to the Eugene Water and Electric Board's (EWEB) Walterville Canal, a half mile northeast of the town of Walterville.
Water monitoring has confirmed the presence of blue-green algae that can produce toxins. These algae levels are likely associated with dangerous cyanotoxin concentrations in the water that can be harmful to humans and animals.
Swallowing or inhaling water droplets, as well as skin contact with water, should be avoided. Drinking water directly from Walterville Pond is especially dangerous.
Oregon Public Health Division officials advise recreational visitors that toxins cannot be removed by boiling, filtering or treating the water with camping-style filters.
People who draw in-home water directly from Walterville Pond are advised to use an alternative water source because private treatment systems are not proven effective at removing algae toxins. However, public drinking water systems can reduce algae toxins through proper filtration and disinfection. If people on public water systems have questions about treatment and testing, they should contact their water supplier.
Oregon health officials recommend that people who choose to eat fish from waters where algae blooms are present remove all fat, skin and organs before cooking, because toxins are more likely to collect in these tissues.
Public health officials also advise that people not eat freshwater clams or mussels from affected water, and that Oregon Department of Fish and Wildlife regulations do not allow the harvest of these shellfish from freshwater sources. Crayfish muscle can be eaten, but internal organs and liquid fat should be discarded.
Exposure to toxins can produce symptoms of numbness, tingling and dizziness that can lead to difficulty breathing or heart problems, and require immediate medical attention. Symptoms of skin irritation, weakness, diarrhea, nausea, cramps and fainting should also receive medical attention if they persist or worsen. Children and pets are at increased risk for exposure because of their size and level of activity.
The public will be advised when the concern no longer exists.
With proper precautions to avoid water contact, people are encouraged to visit Walterville Pond and enjoy activities such as hiking, biking, picnicking, fishing and bird watching. Boating is safe as long as speeds do not create excessive water spray, which could lead to inhalation risk.
