Between 1986 and 1992, a lake appeared east of the city, along Las Vegas Wash, a riparian area. This is Lake Las Vegas, a privately owned lake that is part of a commercial residential resort. You can see that unlike Lake Mead, it is fringed with land that has been cleared for building. This appears as a bright halo in the 1992 Landsat image. After 1992, golf courses and residential and resort buildings were built up along the shores of the southern portion of the lake.
