The community called Lake Wylie, South Carolina — the unincorporated area along Highway 49 and Highway 274 — lies in York County, South Carolina. It has no town government of its own; county services, the York County Sheriff’s Office and the Bethel and Lake Wylie fire districts cover it, and children attend Clover School District schools.
The lake itself is shared. Its northern and eastern shoreline sits in Mecklenburg County, North Carolina (Steele Creek and the Palisades side of Charlotte) and Gaston County, North Carolina (Belmont and Mount Holly). The southern and western shoreline is York County, South Carolina, touching Clover, Tega Cay, Fort Mill and River Hills. The state line runs down the middle of the water, which is why boating, fishing licences, property taxes and school assignment can all change from one cove to the next.
The water surface is managed by Duke Energy under its federal licence, so docks, shoreline vegetation and lake-use permits are handled by the utility rather than by any town or county.
