The North Carolina Department of Environmental Quality Division of Water Resources (DWR) advises the public to avoid contact with green or blue water in parts of the Chowan River in Chowan and Bertie counties due to an algal bloom that has lingered in the area since Aug. 16. The bloom has been observed from near the community of Rockyhock to below the U.S. 17 bridge over the Chowan River near Edenton.
