Following the discovery of a possible case of whirlpool disease in the southeastern Rocky Mountains of British Columbia, all bodies of water in Kootenay and Yoho National Parks were temporarily closed for the next five months.
According to a news release from Parks Canada, this is the province’s first detection of the microscopic fish-killing parasite.

The disease is spread in the southeastern Rocky Mountains of British Columbia.
How to prevent the disease?
To prevent future spread, the government said it will block the shorelines, water bodies and tributaries of Emerald Lake, Peaceful Pond, Lone Duck Pond and Emerald River until March 31, 2024.
It was previously claimed that the parasite, a recognized invasive aquatic species, is almost impossible to eliminate once established.
Although preliminary testing results revealed suspected cases of whirlpool disease in the Kicking Horse River, Wapta Lake, Finn Creek, Monarch Creek and the confluence of the Emerald and Kicking Horse rivers, Parks Canada officials say they are further sampling the Kicking Horse and Kootenay rivers. .

According to the Canadian Food Inspection Agency website, whirl disease affects several species of trout and salmon and mountain whitefish. It can also cause skeletal abnormalities in younger fish.
People can unintentionally spread the disease, although the CFIA says there is no risk to human health.
