1. Area of land that drains water into a stream, river, lake, marsh, bay or an underground aquifer. Water from rainfall and irrigation that runs through the surface of the soil (what is called runoff water) flows into storm drains, streams and rivers. Watersheds are more than just drainage areas in or around our communities. They are necessary to support habitat for plants and animals and provide drinking water for people and wildlife. They also provide us with the opportunity to have fun and enjoy nature. (Free translation from the original: http://www.cridlac.org) 2. Geographic area delimited by the respective watershed whose surface flow converges to its interior being captured by the drainage network which refers to it.
