From Lake Hopatcong, to Greenwood Lake, to Lake Musconetcong, the toxic cyanobacteria that turns water green has prompted the state DEP to advise against swimming, water skiing and other activities at several lakes and bodies of water across the state. Contact with algal blooms can result in rashes, flu-like symptoms and other physical effects. The blooms can also sicken or kill animals that ingest the water.
But, at Lake Mohawk, jet skiers and boaters could be seen enjoying water sports and dockside restaurants. There is no cyanobacteria in the lake, and area residents want to keep it that way.
