The Calgary herald is reporting today the the entire bow river watershed, from Banff national park all the way to the confluence with the south Saskatchewan river, including all tributaries, is infected with whirling disease. Testing is being done on other watersheds to determine if the disease has spread further.
This is not a surprise at all I would expect the south sask and the old man are also effected. As well as testing expands they will fine many of the waterways in Alberta and even stuff on the Bc side of the border are also affected.
