Counties

All 27 West Virginia counties, ranked by average lake water quality. Compare them against every county nationwide in the county rankings, browse the full directory of lakes, or pick a different state.

West Virginia lists 38 lakes across 27 counties, 4 of them with a recent clarity, phosphorus or algae reading. The rest are here because they are real named lakes, listed for their size, depth and location.

By surface area the largest lake here is Summersville Lake, at about 2,790 acres, and 12 of the lakes in this index cover more than 500 acres. Size is worth knowing before you go: a large deep basin buffers nutrient inputs by sheer volume, while a shallow one warms quickly and can turn over its whole water column in a single summer storm.
