Some waterproof concealers that are beyond excellent are the Amazing Cosmetics Amazing Concealer, and the Lancome Effacernes Waterproof Concealer and the Tarte Smooth Operator Amazonian Clay Waterproof Concealer. They're all long wearing and waterproof, and provide great coverage!
Hope this helps
For your eyes or for blemishes? If it's for blemishes -- one concealer that I can attest really IS waterproof is Make Up For Ever Full Cover Concealer. It's pricey, but an excellent investment -- it's so pigmented that a tiny, tiny amount goes a long way. I have had my tube for ages and it's at least 85% full. When I was swatching the shades, I tested them on my forearm / wrist. I happened to be going to the gym afterward, and I'm telling you, this stuff lasted through my (sweaty) 6-mile run. It stays on!

I have tried both of these items in water and they are very waterproof
Lancome Effacernes Waterproof Concealer
Make up forever face and body foundation waterproof (it has a sheer coverage which is buildable)
If you need any other waterproof items, let me know.

I agree with the comment below about the makeup forever concealer i have used both the stick and the full coverage. The stick did nothing for me. It's more for the people who barely need any coverage and just a slight light under eye look. The full coverage seemed to get a little cakey and creasy under my eyes after awhile. I have recently tried the sephora full coverage concealer in light clair and it has worked just as good if not better. PLUS it's only $16! You wont regret at least trying! Hope this helps!
