So I've been scouring the web for this match forever. It looks like there are some INCREDIBLE underwater shots that I just need to see. What I know so far is that there was a youtube video done in 2011 that contains these stills:

For what it's worth, here is the rest of the video too: https://motherless.com/G00285A5/B44332D
So what match is this!? It must have happened before 2011, but I can't figure it out. The suits worn are pretty unique so that definitely helps to narrow it down, but so far no dice.
One thought, it might be that this footage is on a non-english site which I don't have access to.
It appears this match was in the 2004 Olympics in Athens, it was group stage of the Women's Water Polo competition and Russia won 9-8.
Seeing footage from the same period really makes it look like you're on the right track! Still looking for that video. I can see the men's HUN vs RUS and at least one other women's event, but not that particular event yet.
