Check the (Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales it has information about all the river systems in the world and also modified elevation data (DEM)

http://hydrosheds.cr.usgs.gov/index.php

Muhammad Farooq

You have to extract watershed from DEM (SRTM 90m, SRTM 30m (available on hydrosheds web) or ASTER 30m using GIS analysis toolbox (like hydrological analysis in ArcGIS)
