PORTLAND, Ore.—Oregon Health Authority (OHA) issued a recreational use health advisory today for Cronemiller Lake due to the presence of a cyanobacteria bloom. The lake is in Benton County.
People should avoid swimming in areas of the lake where blooms are, as the major risk of exposure is from ingesting water. These toxins are not absorbed through the skin. However, if you have skin sensitivities you may get a puffy red rash.
People are encouraged to visit Cronemiller Lake and enjoy activities such as hiking, biking, picnicking and bird watching. Boating is not allowed at Cronemiller Lake.
Drinking water
Drinking water directly from areas of the lake affected by a bloom is especially dangerous. Toxins cannot be removed by boiling, filtering or treating water with camping-style filters.
Children and pets
Children and pets are at increased risk for exposure because of their size and levels of activity. Dogs can get extremely ill and even die within minutes to hours of exposure to cyanotoxins by drinking the water, licking their fur or eating the toxins from floating mats or dried crust along the shore. This is regardless of a recreational use health advisory in place.
Be aware that dogs can become ill and die from water intoxication after drinking excessive amounts of water while swimming or fetching objects for long periods of time. Intoxication is a potentially fatal disturbance in brain function resulting from an imbalance of electrolytes in the body. Water intoxication and heat stroke can cause similar symptoms as exposure to cyanotoxins.
Symptoms
Exposure to cyanotoxins can be serious and cause a range of symptoms. Symptoms may be similar to food poisoning such as stomach cramping, diarrhea, nausea and vomiting. Symptoms may also be more serious, such as numbness, tingling, dizziness and shortness of breath. These symptoms may require medical attention. Dogs can experience weakness, difficulty walking, seizures, lethargy, loss of appetite and more. If your dog exhibits any of these symptoms after swimming, seek veterinary treatment as quickly as possible.
Fishing
Although fishing is not allowed at Cronemiller Lake, please know that fish caught from areas where cyanobacteria blooms are present may pose unknown health risks. Fat, skin and organs should be removed before cooking or freezing. Toxins are more likely to collect in these tissues. Fillets should also be rinsed with clean water.
