Lake Chipican Mystery
Sarnia city crews are still trying to determine why Lake Chipican in Sarnia’s Canatara Park is a fluorescent khaki green colour.
Parks and Recreation Director Ian Smith says it remains a mystery.
The city has spent tens of thousands of dollars to stop oil buried in a former industrial dump near the lake from entering the pond and there is no sheen on the water.
Some think oxygen depravation and algae might be to blame but that has not been proven.
