"Daylighting streams" refers to the process of restoring or uncovering streams that have been buried or diverted underground. In urban areas or heavily developed landscapes, streams are sometimes buried in pipes or culverts, primarily for the purpose of land development or flood control. Daylighting involves removing or altering these structures to expose the stream to the surface again.

By daylighting streams, the aim is to restore the natural flow and function of the stream, as well as the associated riparian habitat. This process often involves reconfiguring the landscape to recreate a more natural channel, incorporating features like meanders, riffles, and pools. Daylighting streams can have several benefits, including improving water quality, enhancing aquatic and riparian habitat, increasing biodiversity, and providing aesthetic and recreational opportunities for communities.

The term "daylighting" is used metaphorically to describe the process of bringing a stream back into the daylight or open air, as opposed to keeping it hidden or confined underground.
