Discussion from McGrain and Currens (1978)
County is in the Mississippian Plateaus area of western Kentucky.
Kentucky Lake marks the southwestern boundary of the county, and the
Cumberland River marks most of the northwestern boundary. Lake Barkley,
a multipurpose reservoir on the Cumberland River, crosses the center
of the county. The two lakes are connected by Barkley Canal on the western
edge of the county, which permits the two impoundments to have a common
normal pool elevation of 359 feet. The lowest elevation in the county,
approximately 305 feet, is on the Cumberland River at the mouth of Livingston
The highest elevations are in the southeastern part of the county. The highest point, 670 feet, is on a ridge on the Lyon-Trigg County line, approximately 2 miles northeast of Lake Barkley.
The area known as the Land Between the Lakes is a hilly area with many
ridgetop elevations exceeding 500 feet. The highest elevations in this
part of the county are found on the drainage divide between Kentucky
Lake and Lake Barkley. Probably the highest natural point here is at
the base of the lookout tower (Hematite triangulation station) in the
southern part of the county, where an elevation of 590 feet is recorded.
Iron Hill, south of Suwanee, is 520 feet.
The elevation of Eddyville, the county seat, is 470 feet. Other elevations are Kuttawa (new), 450 feet; Kuttawa (old), 390 feet; and Lamasco, 560 feet. The highest elevation in Vista Ridge Park, located on a conspicuous northeast-trending ridge at old Kuttawa, is 580 feet.
