WARNER COUNTY - Due to elevated levels of fecal bacteria, Alberta Health Services (AHS) is advising the public to avoid all exposure to the water in the Milk River at the Writing on Stone Provincial Park beach, effective immediately.
Elevated levels of fecal bacteria were detected via testing of the river water at this beach location. At current levels, gastrointestinal illness may result from ingestion of the water at this beach at Writing-on-Stone Provincial Park. As well, there is the possibility of skin, ear and eye infections with water contact.
