Are you concerned about water damaging the camera or the lens, put them in a plastic bag with only the front element exposed and use a clear glass filter to protect the lens. If only mist on the front element, still a clear glass filter and clean it before each shot (The reason for the filter is that you will be cleaning it frequently, and that way you won't have to worry about the lens). If you don't believe in protective filters this just may be the right time to use one.
Very good advice. I shoot a lot of waterfalls and always bring with me a couple of microfiber clothes and an extra filter. Cover my lens and camera with a gallon freezer bag or bigger use a rubber band around my lens. This may sound like a lot of work but when you get used to doing it moves right along. :D
