I went through the website but the elevation it is showing is not accurate.. can you please explain me how to derive the depth data from the website?

sure, first can you explain what you tried? and why you say it is inaccurate?
perhaps share screenshots showing what you see vs what you expect to see

I have seen point data of altimertry data in Maharashtra coastal region. But the river depth data is not available. It is only showing elevation data. Can you explain how to find the data. Here I have attached one screenshot please have a look on that.

hmm, ok, it seems the region you're interested in may be difficult.
the altimetry data is useful for river depth if there is some period during the year when the river runs dry.
in that case you can use altimetry data from two different timestamps, winter & summer to see the change in water levels.
the image attached shows 'photon data' which gives you a cross section profile of river elevation for the month of April 2019.
but since the river isn't running dry it's hard to estimate the depth of the water
moreover, the west flowing rivers are narrow in the hills so that also makes it difficult to find a good profile
alternatively you can try the http://tamcnhp.com/wris/#/waterData (India WRIS) website.. this is being revamped so it doesn't show much at the moment
but it may in the future.. there again, you will get river gage level (in metres above MSL) not river depth directly
