It is quite a problem at times here. Makes it impossible to sit on the beach when present.
Whenever we get several hot days in the spring the Regents canal is always plagued by blooms of toxic duckweed. Last year they removed 120 tons of the stuff.
This is not my pic but this is a part of the canal east of me called the Limehouse Cut, not far from the Olympic stadium.
