Oldman River watershed infected with whirling disease
The watershed of the second major river feeding into the South Saskatchewan has been declared infected with whirling disease.
In a news release issued on Monday, the provincial government said the entire watershed of the Oldman River has been infected with the disease. The declaration covered all streams, lakes, and rivers feeding into the Oldman River, including those in Waterton Lakes National Park.
The affected zone ended at the confluence of the Oldman River and South Saskatchewan River.
Areas in Alberta outside the Bow River and Oldman River watersheds were previously declared as a buffer area, and were not impacted by the declaration.
