The Canadian Food Inspection Agency (CFIA) declared the entire Oldman River watershed infected on Monday, including all streams, creeks, lakes and rivers feeding into the river. This map shows the area that was previously declared infected with whirling disease, in the Bow River watershed, before it spread southward into the Oldman River watershed. A deadly fish disease that has already spread through Banff National Park has now infected a wide swath of territory to the south, including Waterton Lakes National Park. Despite the declaration, Alberta Environment and Parks said there are currently no plans to change fishing regulations in the Oldman River basin.
