High Rock Lake
North Carolina's second-largest lake — 15,180 acres across Davidson and Rowan counties, built for an aluminum smelter that closed in 2007. What buyers need to understand first: this isn't Duke Energy's lake, and the rules are genuinely different.

High Rock Lake was impounded in 1926-1928 by the Tallassee Power Company, a subsidiary of the Aluminum Company of America, as the northernmost of four hydroelectric dams built to power Alcoa's Badin Works aluminum smelting operation 16 miles downstream. That smelter closed permanently in 2007, and in February 2017 Alcoa sold the entire Yadkin Hydroelectric Project — High Rock, Narrows, Falls, and Tuckertown dams — to Cube Hydro Carolinas. Ontario Power Generation acquired Cube Hydro in 2019 and now operates it under the Eagle Creek Renewable Energy name for billing purposes, though the licensed entity on record with FERC remains Cube Yadkin Generation LLC.
At 15,180 acres, High Rock is North Carolina's second-largest lake behind Lake Norman, spanning Davidson and Rowan counties across 365 miles of shoreline. Full pond sits at 655 feet elevation — noticeably lower than Norman's 760-foot reference, reflecting a different point on the Yadkin River system entirely. Where High Rock diverges sharply from Norman is water level behavior: as the uppermost reservoir in a four-dam chain historically operated as a "store and release" facility, High Rock has seen documented drawdowns of up to 15 feet — a fluctuation range far beyond anything Norman experiences, and something every buyer here needs to understand before assuming year-round dock depth.
What Buyers Need to Know First
Cube Yadkin, not a county or a homeowners association, controls what can be built on this shoreline — and its process is more hands-on than Duke Energy's at Lake Norman. Before Cube Yadkin will issue a construction permit for a new pier, it requires a mandatory on-site meeting between the property owner and a Cube Yadkin representative, and the property owner's house must already be under roof. Neither of those requirements exists at Lake Norman. Buyers assuming the two lakes work the same way because they're both hydroelectric reservoirs in the same state are in for a surprise — the full breakdown is on our dock permits page below.
