Geo-referencing & digitizing map is not an option since the actual scale at which map was made is not known and delineation of actual accurate area will not be feasible. (Same is true by calculating via drainage network using DEM) All help will be greatly appreciated. :)

I agree with Mr.Patil, you can extract drainage basin using Cartosat Dem data or SRTM dem data.
