Key Points:
  • Smith Mountain Lake is the deepest lake in Virginia at 250 feet deep.
  • It is a manmade lake built between 1960 and 1963 by damming the Roanoke River.
  • The deepest body of water in the state is the John H Kerr Reservoir, much of which is located on the other side of the Virginia border in North Carolina.

Virginia is one of the original 13 colonies and known as the “birthplace of America” having the first permanent settlement, Jamestown. The varied landscape of the state has a little of everything from the Appalachian Mountains to the Atlantic Ocean coastline. The Chesapeake Bay is on the eastern border and major rivers like the Potomac, Rappahannock, York, and James all flow through the state. Some of those rivers are so wide you think they are lakes, but there are plenty of good-sized lakes throughout Virginia.

When it comes to the deepest lakes, they are often some of the biggest lakes. Many times man-made reservoirs created by damming local rivers create the deepest lakes. Is the biggest lake in Virginia also the deepest lake? What about the best fishing? Does the deepest lake in Virginia have the biggest fish? Let’s find out all about the deepest lake in Virginia!

Striped bass (stripers) are also popular fish on Smith Mountain Lake. To find the biggest catches you will want to fish the lower main lake in the summer. Other fish on the lake include crappie, channel catfish, flathead catfish, white catfish, sunfish, and white perch.

Why Is the Kerr Reservoir Also Called Buggs Island Lake?

Folks in North Carolina refer to the lake as “Kerr Lake,” named after the former North Carolina Senator John H. Kerr. While the name also applies in Virginia, some folks in Virginia call it Buggs Island Lake after Samuel Bugg who was an early settler in the area. Below the dam is Buggs Island, which was named after Samuel Bugg and during the building of the dam it was called the “Buggs Island Project.”

How Does the Deepest Lake in Virginia Compare to the Deepest Lake in the U.S.?

The deepest lake in the U.S. is Crater Lake in Oregon. Crater Lake is 1,949 feet deep! Compared to Smith Mountain Lake it is about 1,700 feet deeper. How does a lake get that deep? Crater Lake was formed at the top of an old volcano. The Mount Mazama volcano erupted more than 7,700 years ago and the top of the volcano collapsed forming a large, deep crater. The crater filled in with water and now we have the beautiful blue waters of Crater Lake. Unlike the finger-like Smith Mountain Lake, Crater Lake is pretty much a circle with two small islands. Wizard Island is the most recognizable island and you can take a boat tour out to the island where you can swim from the shore. Most activities are restricted on the lake to keep invasive species out of the crystal blue water.
