A "water-source" refers to any natural or artificial location where water is found. This can include rivers, lakes, springs, and even underground aquifers. These sources are essential for providing fresh water for drinking, irrigation, and supporting ecosystems. For example, a river can be a vital water-source for nearby communities and wildlife. In addition to natural sources, there are also man-made water-sources like reservoirs and wells. Reservoirs are created by damming rivers to store water, while wells tap into underground aquifers. Both types of water-sources play a crucial role in ensuring that people have access to clean water for daily needs and agricultural activities.
