Does it look like my surge has passed?

Ok ladies so for the past 36 hours I've been getting obviously positive opk tests, but they didn't seem to be fading off, as far as research shows till the surge has actually passed ( I.e tests start going negative) the egg isn't actually released yet, do they appear to be getting any lighter?
Bottom one was this morning at 10am
Middle was this afternoon at 3pm
Top was this evening at 8pm

I'm not sure whether fluid intake through out the day would make any difference either.

Thanks ladies xx

The bottom looks the darkest to me.
