Hendersonville is a city in Sumner County, Tennessee, on Old Hickory Lake. The population was 51,372 at the 2010 census. Hendersonville is part of the Nashville Metropolitan Statistical Area and is located 18 miles northeast of downtown Nashville. The city was settled around 1784 by Daniel Smith, and is named for William Henderson. In 2009 Hendersonville was named as one of the ten best cities for families by Family Circle Magazine.
Hendersonville was settled circa 1784 by Daniel Smith when he began work on Rock Castle. In 1790, William Henderson, for whom the area was named, settled in. With the completion of the Old Hickory Dam in 1954, Hendersonville started to grow into the most populous city of Sumner County and one of the most populous suburbs of Nashville, along with Franklin and Murfreesboro. The city of roughly 250 was incorporated in 1969 under the leadership of L.H. "Dink" Newman, and over the next decades has been one of Tennessee's fastest-growing cities. The city contains around 0.7% of the population of Tennessee. During the Civil War, Monthaven, a historic home on the National Historic Register, was used as a field hospital.
In 2007 a risk was identified that the trouble-prone Wolf Creek Dam in the neighboring state of Kentucky might break, which could have resulted in a complete inundation for the lower lying parts of Hendersonville. Since then extensive repairs have been performed on the dam, and the maximum level of water behind it has been lowered, thus reducing the pressure on the structure and resolving the identified flood risk.
