“THIS INCREASE COULD NEGATIVELY AFFECT THE ORGANISMS IN THE LAKE”

Diver Haluk Mayhoş, stating that they frequently dive in the lake, said they had encountered similar formations before, adding, "We also saw them at some points during a dive about 10 days ago. Such formations are considered normal with the warming weather. However, this increase could negatively affect the oxygen level in the lake and the organisms in the ecosystem."
