Water that flows out of the river's headwaters continues down the river's channel until it reaches a large body of water. Along the river's channel are river banks, which are home to many different kinds of wildlife and vegetation. Areas called "floodplains" are flat, low areas beside a river that fill up with water when the water level in a river becomes too high. Heading downstream, the water in a river will eventually reach the delta, or mouth, where it slows down and enters another body of water, such as a lake, ocean or wetland.
