There is a water polo group. Or at least there was... Call the Intercontinental Bay Club-- they should have information about it. But I think this is men's group, not really for kids... There is also a Qatar National Team. If you get in touch with them, maybe they can point you in the right direction.

Maybe the american school???

If you find anything out, i'd love to know, I'm an ex-polo player, but haven't found any opportunities for womens' water polo here.
