Stream restoration channel bottom rock
Streams change over time, both naturally and from human interference. Changes can alter the natural balance of the stream corridor, resulting in reduced water quality, wildlife habitat and increased erosion. When streams are restored to a more natural state, these detrimental effects can be reversed, or at a minimum their negative impact reduced. Stream corridors can be restored in several different ways, but the most beneficial to the environment is natural stream restoration. Natural stream restoration is a multi-step process in which objectives are defined, the stream is assessed, the best course of action is determined, and restoration design and construction occurs.
