Toxic Algae Warnings – Not Just Lake Winnipeg – All Over North America

I had the opportunity to take a trip on the Namao, the research ship of the Lake Winnipeg Research Consortium, earlier this week. It was very interesting to see some of the water sampling being conducted at several stations around the lake.

The satellite images on the LWRC’s website have drawn attention to the large blue-green algae bloom that is appearing in the north basin of Lake Winnipeg and pointed out as well, the bloom that was starting to develop around Grand Beach. That bloom became all too obvious to people visiting the beach last weekend. 

I was curious to learn how common these blue-green algae blooms are becoming and was not too surprised to see warnings about them in several American states, Oregon, Ohio and Iowa, most recently. Some of the  blue-green algae contain Microcystin – LR which contains toxins affecting the liver and other organs. So it is potentially a serious health threat to both humans and animals, with several documented cases of dogs dying after going into water with blue-green algae present.

I’m interested in learning about where else in Canada there are blue green algae problems so let me know if there algae problems near you. This is a significant problem that we can all be part of fixing!
