Reports of algae and seaweed on the rise; however, upon investigation the algae/seaweed is not harmful or invasive

Reports of algae and seaweed to the Lake Norman Marine Commission (LNMC) and Duke Energy have risen in that few weeks. The LNMC has forwarded these reports to the North Carolina Department of Environment & Natural Resources (NC DENR) and to Duke Energy. NC DENR reports from its investigation that the algae/seaweed is not harmful, is a natural occurrance in the ecosystem and will die out when the lake temeratures drop in the fall. Duke Energy reports that while some individuals thought the seaweed was hydrilla (an invasive aquatic weed) in actuality it was chara, not an invasive weed and not harmful. Attached is a factsheet from Duke Energy about chara and a weed information sheet from NC DENR.
