Is there a waterproof carrying case for my Digital SLR?

I take ALOT of outdoorzy photos so I need a tough carrying case. I'm also planning on going on a river trip this summer and I'd like my case to be waterproof so my Nikon D7000 doesn't get water damage.

Adorama and BH Photo carry underwater housings for taking pictures in wet conditions. Underwater housings for DSLR's are very expensive.
Northwest River Supply carries many bags and boxes that can protect your gear in transport.

I have a Pelican case for my Camera, They are watertight and covered by a lifetime warranty. I have dropped my Pelican case down a rocky hill with my camera inside. No damage. Pelican cases also have pick and pluck foam inside them to fit your camera just right, they come in many sizes and colors so you can fit all your accessories in there too. I bought my Pelican case at this link
