Most good athletic or swim stores sell waterproof weights that velcro around your ankles or wrists to increase resistance. They will turn water aerobics into a serious workout, and swimming lengths into a thigh burner.
Good luck! Swimming is one of my favourites too, probably because I don't feel sweaty.

After you look at these 15 videos, there are also other water exercise links on the page to explore.
With my knee injury, this is almost the only kind of exercise I did this summer.
