An update to a story we brought you last month about whirling disease in Banff National Park.
The Canadian Food Inspection Agency confirms the disease has been found in the upper Bow River, downstream from the intersection at the Cascade River.
The province says a three-point action plan was developed after whirling disease was found in Johnson Lake on August 23rd.
As part of the plan, the province issued a precautionary quarantine on all commercial fish culture operations until the facility is cleared of the disease.
Sample results from the Sam Livingstone Provincial Fish Hatchery in Calgary and the Cold Lake Provincial Hatcheries have tested negative, while samples are also being collected from basins adjacent to the Bow, Oldman and upper Red Deer River watersheds.
