Oregon Health Authority lifts recreational use advisory for Malheur Reservoir

OHA lifted the advisory based on sampling that confirmed levels of cyanotoxins in Malheur Reservoir to be below recreational guideline values for people, and because the summer recreational season has ended. Although the levels detected are below the recreational use values for people, they continue to be well above OHA’s educational guideline values for dogs. Owners and hunters should be aware of the potential exposure to their pets while at the reservoir, especially shallow, marshy areas where cyanobacteria blooms can form, or cyanobacteria can be present on green algae, growing from the sediment or on rocks.
