CHARLESTON, S.C. (WCSC) – Officials in Dorchester and Colleton counties are urging residents along the Edisto River to take precautions as the river move toward flood stage. The Colleton County Sheriff’s Office and Fire-Rescue ask residents to avoid “boating, floating and sight-seeing” on the Edisto River and warn boaters to create no wake if they must travel through. They say the creation of waves can cause water from the already rising river to flood homes and impact electrical sources.
