As Queenstown Lakes District Council and the Otago Regional Council continue to investigate what has turned Lake Wakatipu a glowing neon green, public speculation is ramping up with suggestions ranging from vehicle coolant to marker dye. Concerned Auckland woman Georgia Rose contacted The New Zealand Herald yesterday afternoon after spotting bright green water gushing out of a stormwater pipe and into the picturesque lake. The mystery bright green liquid rushes out from Horne Creek into Lake Wakatipu yesterday. Herald readers had a few suggestions on what the liquid could be - anything from coolant to marker dye. The marker dye tended to stay in the water for "some time" but depending on the movement of the creek's water, it should be gone today.
