Oregon Health Authority (OHA) issued a recreational use health advisory last week for Lake Billy Chinook in Jefferson County, due to the presence of cyanotoxins above Recreational Use Value (RUVs). OHA’s Recreation Use Values (RUVs) are made to protect the most vulnerable people, including children.
People should not swim or do activities where they might swallow water or breathe in water spray if there is a harmful algae bloom in a river, lake, or reservoir. Swallowing or breathing in the water is what can make people sick—the toxins do not soak in through the skin, but people with sensitive skin might get a red, puffy rash.
Safe ways to enjoy Lake Billy Chinook
OHA still encourages people to visit Lake Billy Chinook and enjoy activities like:
- Fishing
- Camping
- Hiking
- Biking
- Picnicking
- Bird watching
- Canoeing
- Kayaking
Boating is safe if you keep speeds low enough to avoid creating a lot of spray, because spray can increase the risk of breathing in toxins.
Drinking water safety
Do not drink water directly from parts of the lake affected by a bloom. Boiling, filtering, or using camping-style filters will not remove toxins. If you have questions about drinking water at nearby campgrounds or day-use areas, contact the campground manager or the local health department.
Some private water treatment systems cannot remove cyanotoxins. People who do not use a well or a public water system and get their home water directly from the lake should use another water source for drinking and cooking.
Symptoms in people and pets
Children and pets have a higher risk because of their size, activity level, and chances of swallowing water.
People exposed to cyanotoxins may have symptoms similar to food poisoning, such as stomach cramps, diarrhea, nausea, and vomiting. More serious symptoms may include numbness, tingling, dizziness, or trouble breathing. Some symptoms may require medical care.
Dogs can get very sick and could die within minutes to hours after exposure. They can be exposed by drinking the water, licking their fur, or eating floating mats or dried crusts along the shore—even if there is no posted advisory. Symptoms in dogs include trouble walking, seizures, low energy, loss of appetite, and more. Seek veterinary care right away if a dog shows signs of illness. OHA recommends keeping dogs on a leash and away from affected water and algae mats.
Safe fishing
Fish caught in areas with harmful algae blooms may carry unknown health risks. OHA recommends not eating fish from these areas. If people choose to eat the fish, they should remove the fat, skin, and organs, which is where toxins can build up, before cooking or freezing. Rinse fillets with clean water.
