Kentucky Lake


Kentucky Dam creates the largest manmade lake in the eastern United States. It backs up the Tennessee River for 184 miles and creates a lake that stretches south across the western tip of Kentucky and nearly the entire width of Tennessee. At maximum normal operating level, Kentucky Lake covers 160,300 acres.

More important than the project's size are the jobs it performs. Kentucky Dam is the spigot that TVA (Tennessee Valley Authority) uses to help control floods on the lower Ohio and Mississippi rivers; it is the gateway to the Tennessee River waterway and is a major generating plant in the TVA power system.

Construction
The huge job of building Kentucky Dam took six years from the start of construction on July 1, 1938, until the reservoir began filling on August 30, 1944. At the peak of construction TVA had nearly 5,000 men at work building the dam and preparing the reservoir area. The dam, which is more than a mile long and rises 206 feet above its foundation, required 1,356,000 cubic yards of concrete and 5,582,000 cubic yards of earth and rockfill. The project cost about $118 million.

Flood Control
The Tennessee is the nation's fifth largest river within the lower 48 states in terms of flow. Kentucky Dam is just 22 miles upstream from Paducah, Kentucky where the Tennessee River flows into the Ohio. Water from the 40,200 square mile Tennessee Valley passes through the dam. This strategic location and the vast flood storage capacity of Kentucky Lake make it possible for Kentucky Dam to reduce or even temporarily shut off the flow of water from the Tennessee to help lower flood crests on the Ohio and Mississippi rivers. With the other dams in the TVA system, it helps provide flood protection to 6 million acres of land in the lower Ohio and Mississippi valleys and reduces the frequency of flooding on another 4 million acres. In the many years since Kentucky Dam was completed, this flood regulation has reduced damages in those areas by millions of dollars.

Did you know that entire towns had to be completely relocated when the Kentucky Lake & Lake Barkely were built? And that thousands of people had to be relocated when the Tennessee Valley Authority (TVA) purchased over 170,000 acres of land to form the national recreation area of Land Between the Lakes (LBL)?
Seems impossible, but It's true.

Navigation
Projects to improve navigation conditions on the lower Tennessee River began shortly after the Civil War, but it was Kentucky Dam and lock which finally provided a first-order channel for today's big inland towboats and barges. Kentucky Lake is the first step in a stairway of navigable TVA lakes that allow modern 9-foot draft vessels to travel the 650-mile-long main river the year round. Since impoundment of Kentucky Lake in 1945, completing this waterway and linking the Tennessee Valley with the 21 state inland waterway system, freight traffic on the Tennessee has grown from 2 million tons a year to more than 31 million tons.

The lock, at the eastern end of the dam, handles more than 2,000 loaded barges a month. This normally requires lifts of about 55 feet between the river below the dam and the lake behind it. A river tow bound upstream may carry steel from the north, grain from the midwest, or petroleum products, chemicals, or ores from the Gulf Coast. Down-bound tows carry a variety of Tennessee Valley products to other regions, including nuclear reactor vessels too large to travel overland.

Power Generation
The five turbine-generators in Kentucky Dam powerhouse have a total capacity of 175,000 kilowatts. They harness the river's flow to generate up to 1.3 billion kilowatt-hours of electricity each year. Some of this water comes from the river's headwaters and already has helped to spin turbines at a dozen other TVA dams as it flows a thousand winding miles down the Tennessee Valley.

Recreation
Kentucky Lake is a magnet for vacationers and fishermen from a wide area of mid- America, with recreation use amounting to some 17 million visits each year. Along its nearly 2400 miles of cove-studded shoreline are many boat docks and resorts, 4 state parks, the Tennessee National Wildlife refuge, 48 public access areas, 2 county parks, 5 municipal parks, 2 state wildlife management areas, 10 group camps and clubs, 92 commercial recreation areas, and 3 small wildlife areas.

Kentucky Lake History
At 8,422 feet, Kentucky is TVA's Longest dam. Construction on the dam began in 1938 and the reservoir began filling six years later. To provide a dry river bed for construction, huge cofferdams were built in three stages, starting on the east side and working to the west embankment. The first stage enclosed 26 acres for workers to construct the navigation lock. In the second stage, 40 acres were enclosed for constructing the powerhouse and 9 of the spillway bays. The third stage enclosed about 30 acres for completion of the remaining spillway bays. The impact Kentucky Dam would have on flood control and commercial navigation was foreseen by TVA designers. Electrical generation was not a top priority in the original design; but today's generators contribute about 1.3 billion kilowatt hours of electricity each year for TVA's power system.

Purchase & View MAPS of Kentucky Lake

Kentucky Lake provides an almost endless amount of things to do, but fishing is arguably the most popular attraction. Just consider the large number of fishing guides and you're likely to agree. However, for the fisherman who wants to head out alone, consider buying a Kentucky Lake map, which shows helpful information such as depth contours, boat ramp locations, fishing tips and more.
