Another algae bloom on the Thames




The Lower Thames Valley Conservation Authority (LTVCA) staff noted another discolouration in the Thames River in Chatham caused by a bloom of blue-green algae on Friday.

The bloom seems to have spread over the weekend and now appears to be forming upstream in the Lower

Thames through Middlesex and Elgin Counties, as well as having flowed downstream to the mouth at

Lake St. Clair.

Overall, the bloom doesn’t seem to be as severe as the one that occurred in late August, but this one covers a larger area.

Some varieties of this algae can produce toxins that are harmful to both humans and animals. People should take a precautionary approach and assume toxins are present, avoid using, drinking, bathing or swimming in the water, and restrict pet and livestock access to the water.
