A flight over the mountains and piedmont of North Carolina will reveal numerous large lakes and reservoirs. Almost all were man-made when rivers were dammed for flood-control and hydro-electric projects.
Eastern North Carolina has numerous oval-shaped, shallow lakes. Most are natural lakes and many are rimmed by swamps and cypress trees containing incredible biodiversity.
This episode Exploring North Carolina explores the mysteries found deep in two of these lakes (Waccamaw and Phelps) and one Tar Heel pond (Merchants Millpond)—each of which is the site of a unique state park.
