Hava a look at OpenStreetMap. Take a look at this relation: http://www.openstreetmap.org/relation/3250963 where Telangana is included. You can download OSM land polygons from here: http://openstreetmapdata.com/data/land-polygons or daily updated data from here: http://download.geofabrik.de/asia/india.html
I just visited the Water Resources Information System of India and noticed that there is a Data Download button under WRIS Connect in its left hand panel. I recommend that you follow where that leads you.
OpenStreetmap seems to have some data: http://www.itoworld.com/map/4?lon=84.67111&lat=24.56236&zoom=7&fullscreen=true You can get the full source data of India from Geofabrik , and filter for the items you are interested in. But don't expect the data to be complete.
