Pickwick Landing Dam is located nearly above the mouth of the Tennessee River, a few miles north of the point where the states of Tennessee, Alabama, and Mississippi meet. This stretch of the river is also a geological boundary between the scattered hills of the Western Highland Rim to the northeast and the flatlands of West Tennessee to the northwest. Most of the land just south of the dam and its immediate lakeshore is part of Pickwick Landing State Park, and Shiloh National Military Park is located a few miles to the north. Pickwick Lake stretches nearly to the base of Wilson Dam at Muscle Shoals, Alabama, and includes parts of Hardin County in Tennessee, Lauderdale and Colbert counties in Alabama, and Tishomingo County in Mississippi. The area around Pickwick Landing Dam is sparsely populated, the nearest community of note being the small community of Counce, Tennessee 2 miles to the southwest. Tennessee State Route 128 crosses the top of the dam, connecting the area to Savannah to the north.
Capacity
Pickwick Landing Dam is high and long, and has a generating capacity of 240,200 kilowatts. The dam's spillway has 22 bays with a combined discharge of. Pickwick Lake has of shoreline and of water surface, and has a flood-storage capacity of. Pickwick Landing Dam is serviced by two locks— one measuring and the other measuring. The locks' lift raises and lowers vessels up to between Pickwick and Kentucky lakes.
Background and construction
Throughout the 19th century, a series of river rapids known as the Muscle Shoals were a major impediment to navigation along the Tennessee River and effectively isolated the upper stretches of the river from the nation's major inland waterways. The construction of Wilson Dam by the U.S. Army Corps of Engineers in the 1920s and the construction of Wheeler Dam by the Tennessee Valley Authority in the 1930s flooded a large section of the shoals, but serious obstacles still remained between Riverton and Florence, especially in the vicinity of Tuscumbia. As Wheeler Dam neared completion in 1935, TVA knew a third dam would be necessary to connect the reservoirs at Muscle Shoals with the lower part of the river. Several private entities had investigated the possibility of building a dam at Parker's Landing, but the Corps of Engineers— which had surveyed the area in the 1920s— suggested TVA build a dam at Pickwick Landing. The Pickwick Landing project was authorized on November 19, 1934, and work began in March 1935. The construction of Pickwick Landing Dam and its accompanying reservoir required the purchase of of land, of which had to be cleared. 506 families, 407 graves, and of roads had to be relocated. Parts of Riverton and Waterloo, Alabama were flooded. The residents of the latter demanded TVA purchase the whole town, claiming the reservoir would destroy property values, but TVA declined, citing a study that suggested the reservoir would not have a serious or detrimental impact on the town's economy. Pickwick Landing Dam's original turbines were among the largest propeller-type turbines in the world at the time in which they were installed. Pickwick Landing Dam was completed and the gates closed on February 8, 1938, although dredge work continued until 1941. The first generator went online in August 1938. The lock was designed by the Corps of Engineers, and its lift was among the highest in the world when the lock became operational on February 19, 1938. Pickwick Landing Dam was constructed at a cost of just over $45 million.
