Using netting and electro-fishing, Parks Canada officials began eradicating fish from Johnson Lake near Banff this week in an effort to stop whirling disease from spreading to other bodies of water. Johnson Lake was stocked with brook and lake trout decades ago. The goal of the eradication is to protect other bodies of water, namely the nearby Two Jack Lake Reservoir and Minnewanka Lake Reservoir, which are currently free of whirling disease. Officials use nets to remove fish from Johnson Lake to protect the area from whirling disease.
