The DA18-250mm is not WR but it is very, very sturdy and well-suited in my opinion. There are numerous reports (in this forum and elsewhere) of the DA18-250mm in snow, mud, sand and wet conditions. Like any zoom lens (except possibly the DA18-135mm), you will need to wipe the extended zoom before you zoom out, to prevent water moisture to enter.
However, let us remember that a WR lens is not waterproof. Please read the fine prints. I have both DA18-250mm and DA18-135mm. I take slightly more care of my DA18-250mm because of the zoom pumping action, but both lenses are very sturdy. And I would take both to the trip. (I have not done rafting but boating incl. chasing tidal bores in very wet conditions. I was all the time in wet suit with a rain coast over, that I use to cover the camera when I did not use it.
*Batteries: take a lot of lithium batteries as pointed by dms. A lot!
*Consider a filter to protect the lens glass. (Valid for any lens.)
*Have a water proof container to store your camera. And a smaller pouch to carry around your neck, possibly inside your rainjacket when you do not use it. This neoprene protection works nicely for a K-30+DA18-250mm:

*Also take some wipes to clean regularly your camera and lens. The body may be WR but it is not waterproof!!! A swim sport towel which can be squeezed easily and packed in a pocket.
Hope that the comment may help and enjoy your ride...
