Surha Tal location - 25.8372981,84.1782309 (near Ballia, UP, India), diameter 7.5 Km.
Devdari waterfall location - 24.95034,83.1726 (near Chandauli, UP, India), diameter 200 meters.
Both looks asteroid impact craters to me. Main chunk of asteroid struck at Suraha Tal location and fragment struck at Devdari waterfall location.
But I would like to concentrate on Devdari waterfall first. The terrain is rocky. Videos of this Devdari waterfall are available on youtube. As you can see in google earth, it looks circular. (05/2012 image is very clear). If this Devdari waterfall 'crater' is not made from the celestial impact, what other possible geological reasons are there which have made this waterfall circular? Remember, the Chandraprabha river is very small and it is not perennial river.
@abhiriksh,
you seem to have written about this very subject at other locations. I always suggest that the first step i to open up all the negative reasons that counter your hypothesis and DO NOT support it being an impact crater.
