The Basin tool delineates drainage basins within the Analysis window by identifying ridge lines between basins. Basin analyzes the flow direction raster to find all sets of connected cells that belong to the same drainage basin. The drainage basins are created by locating the pour points at the edges of the Analysis window (where water would pour out of the raster), as well as sinks, then identifying the contributing area above each pour point.
