Question: What is a former name for the river on which Guntersville, Alabama was founded?
Context: The Downtown Guntersville Historic District is a historic district in Guntersville, Alabama.  The district includes most of the central business district of Guntersville, as well as some houses.  The town was founded in the 1820s as a port on the Tennessee River.  Most of the town was destroyed during the Civil War, although the Henry-Jordan House was spared.  The business district began to rebuild after the war, and development was spurred in the late 19th and early 20th century by the Nashville, Chattanooga, and St. Louis Railway and by manufacturing firms.  The opening of Guntersville Dam by the Tennessee Valley Authority in 1939 turned Guntersville into a peninsula, and created tourism and recreation opportunities on the new lake.  Many commercial buildings were constructed after World War II until 1964, in contrast to many small-town downtown areas.  Popular architectural styles from the time are represented, including elaborately decorated Victorian, simpler commercial brick styles, and post-war streamlined styles.  Notable contributing properties in the district are the Albert G. Henry, Jr., House, the Henry-Jordan House, and the Guntersville Post Office, all of which are individually listed on the National Register of Historic Places.  The district was listed on the National Register in 2012. The Albert G. Henry Jr.  House is a historic residence in Guntersville, Alabama.  It was built in 1895 by Albert G. Henry Jr., a prominent merchant in the town.  Henry's grandfather came to Marshall County in 1828, establishing a mercantile business along the Tennessee River.  His son, Albert Sr., continued the business, becoming the dominant store in Guntersville by the beginning of the Civil War.  After the war, he extended credit to his patrons to help rebuild the area.  Albert Jr. followed his father into business, becoming the only millionaire in Alabama in 1880.  He built the two-story, Queen Anne-style mansion in 1895, which features a tower, large wraparound front porch, and extensively detailed woodwork.  It sits across from the Greek Revival Henry-Jordan House, built by Albert's brother, Pat, in 1877.  The house was listed on the National Register of Historic Places in 1989. Marshall County is a county of the U.S. state of Alabama.  As of the 2010 census the population was 93,019.  Its county seat is Guntersville.  A second courthouse is in Albertville.  Its name is in honor of John Marshall, famous Chief Justice of the United States.  Marshall County is a dry county, with the exception of the four cities of Albertville, Arab, Guntersville, and Boaz. Guntersville Dam is a hydroelectric dam on the Tennessee River in Marshall County, in the U.S. state of Alabama.  It is one of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s as part of a New Deal era initiative to create a continuous navigation channel on the entire length of the river and bring flood control and economic development to the region.  The dam impounds the Guntersville Lake of 67900 acre , and its tailwaters feed into Wheeler Lake. Lake Guntersville State Park is a publicly owned recreation area located on the far north side of the city of Guntersville in Marshall County, Alabama.  The state park occupies 5909 acre on the eastern shore of Guntersville Lake, a 69000 acre impoundment of the Tennessee River.  The park features resort facilities and is managed by the Alabama Department of Conservation and Natural Resources. The Tennessee River is the largest tributary of the Ohio River.  It is approximately 652 mi long and is located in the southeastern United States in the Tennessee Valley.  The river was once popularly known as the Cherokee River, among other names, as many of the Cherokee had their territory along its banks, especially in eastern Tennessee and northern Alabama.  Its current name is derived from the Cherokee village "Tanasi". South Sauty Creek is 32.25 mi long with a drainage area of 125.8 sqmi , and is a tributary to the Tennessee River.  The river rises in DeKalb County, Alabama, and flows generally southwest along Sand Mountain from its headwaters before turning generally west and flowing off of Sand Mountain, through Buck’s Pocket, terminating shortly afterwards into Lake Guntersville in an area known as Morgan's Cove.  South Sauty forms the Buck’s Pocket canyon as the creek falls from the north side of Sand Mountain (Alabama). Wheeler Lake is located in the northern part of the United States state of Alabama, between Rogersville and Huntsville.  Created by Wheeler Dam along the Tennessee River, it stretches 60 miles (96.5 km) from Wheeler Dam to Guntersville Dam.  It is Alabama's second largest lake at 67,100 acres (272 km²). The Alabama and Tennessee River Railway (reporting mark ATN) is a shortline railway operating (via lease) over trackage formerly operated by CSX Transportation.  The line's western terminus is a junction with the CSX (former Louisville and Nashville Railroad) main line in Birmingham, Alabama, near CSX's Boyles Yard.  The eastern terminus is Guntersville, Alabama, near the Tennessee River.  The parent company of the ATN is OmniTRAX, a major operator of American and Canadian short lines. Widows Bar Lock and Dam was a dam once located along the Tennessee River in Jackson County, Alabama, USA.  It was situated 407 mi above the mouth of the Tennessee River, near the river's confluence with Widows Creek.  The dam was completed 8 September 1924, and was designed and operated by the U.S. Army Corps of Engineers.  It was serviced by a 60 ft by 265 ft navigation lock.  When the Tennessee Valley Authority took control of flood control and navigation improvement operations in the Tennessee Valley in the 1930s, Widows Bar was considered too high maintenance, and it was dismantled as part of the construction of Guntersville Dam.
