Las Vegas Wash is a 12-mile-long channel which feeds most of the Las Vegas Valley's excess water into Lake Mead. The wash is sometimes called an urban river, and it exists in its present capacity because of an urban population. The wash also works in a systemic conjunction with the pre-existing wetlands that formed the oasis of the Las Vegas Valley. The wash is fed by urban runoff, shallow ground water, reclaimed water, and stormwater.

The wetlands of the Las Vegas Valley act as the kidneys of the environment, cleaning the water that runs through it. The wetlands filter out harmful residues from fertilizers, oils, and other contaminants that can be found on the roadways and in the surrounding desert.
Near its terminus at Las Vegas Bay, the wash passes under the man made Lake Las Vegas through two 7 foot pipes.

History
Before development in the valley above the wash, it was able to contain the flows from rain water that fell in the valley and hills above. When the first sewage treatment plant went on line, the flows began increasing to the point that the channel expanded in size as the increased flows eroded the wash's stream-banks.
This erosion also deepened the channel draining one of the largest desert wetlands in the U.S. southwest as the water flowed down the channel rather than flooding the wetlands area. This has had several consequences among them, increased flows of silt into Lake Mead, fewer migratory birds, reduced water polishing from the native plants, and infestation of invasive plant species such as African Tamarisk (Tamarix africana) and Sahara Mustard (Brassica tournefortii).
