Light shinning through water like a bunch of spotlight

[onesee]

Hey folks, I am trying to recreate a scene similar to THIS. I want to get the look of light shinning through in multiple area like that image. My scene has vrayenvironmentalfog and water setup. I tried using a vray light with a b/w image but it doesn't look anything like that. Is this the right path and how would you attempt at animate something like this? Appreciate any help.
