The Grand River Dam Authority (GRDA) issued an E. coli advisory for Grand Lake, Lake Hudson, and parts of the Illinois River due to high E. coli levels, likely caused by heavy rainfall. Affected areas include Elk River, Wolf Bay, and several sections of the Illinois River. GRDA advises swimmers to avoid swallowing water, wear nose plugs, and wash open cuts. More details on E. coli are available from the Oklahoma State Department of Health, and GRDA will continue to monitor the situation.
