Biggest Lake in Virginia: Smith Mountain Lake (20,600 acres)

Smith Mountain Lake is Virginia's largest inland lake per the Virginia Department of Wildlife Resources. Below: 50 Virginia lakes ranked by surface area.

The largest lake in Virginia is Smith Mountain Lake at 20,600 acres , in Bedford and Franklin County, according to the Virginia Department of Wildlife Resources. John H. Kerr Reservoir (Buggs Island Lake) is larger at 48,900 acres. Virginia's largest lake overall, but this USACE reservoir straddles the state line -- Mecklenburg, Charlotte and Halifax counties in Virginia and Granville, Vance and Warren counties in North Carolina.

Reading Virginia's size profile

Virginia's largest lake by surface area is Dam Lake in Pittsylvania County, spanning 20,400 acres. Most of Virginia's biggest waters are reservoirs — dammed river valleys built for water supply, flood control, and recreation, so their footprints shift with pool level.

Surface area is a poor proxy for water quality on its own — a large lake can hold a clean, deep core and a nutrient-loaded bay at the same time. Each lake below links to its full report card with grade, clarity, depth, and EPA impairment status. Area figures come from state DNR surveys and the USACE National Inventory of Dams; grades come from EPA and state monitoring data.

Frequently Asked Questions

What is the largest lake in Virginia?

Smith Mountain Lake, at 20,600 acres, in Bedford and Franklin County. John H. Kerr Reservoir (Buggs Island Lake) is larger at 48,900 acres. Virginia's largest lake overall, but this USACE reservoir straddles the state line -- Mecklenburg, Charlotte and Halifax counties in Virginia and Granville, Vance and Warren counties in North Carolina. Source: Virginia Department of Wildlife Resources, 2026-07-30.

How is lake surface area measured?

Surface area comes from state DNR lake surveys and, for reservoirs, US Army Corps of Engineers (USACE) National Inventory of Dams records. Area is reported in acres at normal pool level. Reservoirs rise and fall with management and drought, so their listed area is the long-term normal rather than a single-day reading.

Are Virginia's largest lakes natural or reservoirs?

Of the top 50 Virginia lakes by area, 32 sit on a dammed river (reservoirs) and 18 are natural basins. Glacial states (MN, WI, MI, NY) skew natural; plains and southern states (MO, IA, ND, OH) skew toward reservoirs built for water supply, flood control, and recreation.

Do larger lakes have better water quality?

Not reliably. Quality varies more within a big lake than between lakes — a large lake can have a clean, deep main basin and a murky, algae-prone bay fed by a tributary, so one grade can mask wide swings. Depth, watershed land use, and how fast the lake flushes matter far more than raw surface area.

How big is the typical Virginia lake in this ranking?

Across the top 50 Virginia lakes by surface area, the median is 298 acres (Bath County Pumped Storage Lake). This list is biased toward the biggest waters; the typical Virginia lake is far smaller.
