Detailed Description
The New Jersey Department of Environmental Protection advised the public to avoid swimming in or contact with Lake Hopatcong water due to a harmful algal bloom confirmed in June 2019 by aerial surveillance. To help study water-quality conditions and the bloom’s severity, the USGS installed a monitoring buoy on the lake in July.
