A drainage basin or catchment basin is an extent or an area of land where surface water from rain, melting snow, or ice converges to a single point at a lower elevation, usually the exit of the basin, where the waters join another waterbody, such as a river, lake, reservoir, estuary, wetland, sea, or ocean.n closed (endorheic) drainage basins the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, dry lake, or a point where surface water is lost underground.
River basins or watersheds are like huge funnels. The water that falls into them comes from rain, snow, irrigation, and discharge from homes or industry. The water flows downward and even though a lot seeps into the ground, it still moves down hill and collects in streams that feed bigger streams and rivers.
