Local Watershed Plans
"The watershed is defined as a unit of natural or disturbed land on which all the water that falls (or emanates from springs) collects by gravity and fails to evaporate and runs off via a common
outlet. The watershed is the basic unit of water supply."

- Peter E. Black, Watershed Hydrology, Second Edition, 1996.
