Sparks is a city in Washoe County, Nevada, United States. The population was 66,346 at the 2000 census. Estimates in 2006 place the population at around 90,000 due to rapid growth in areas such as Spanish Springs, Wingfield Springs, and D'Andrea. Although Sparks was originally distinct from Reno, they have both grown toward each other to such a degree that today the border between them is purely political. They are often referred to as a twin city. Sparks apartments for rent comparison page shows most up to date rent information on Sparks apartments and houses.
