I've been using a waterproof dry bag from Cabela's for several years now (think "reverse" use of a dry bag).  It only takes an instant to fill out in the lake (although getting it back over the gunwales is a bit like landing a whale), I dispense water via the air-bleed valve and I either drape it over a log, rock or hang from a tree as a "dispensing station."  It also dumps easy when clearing camp and rolls up into a relatively small space that I can stuff.  After the trip, I can turn it inside-out for cleaning.

Only downside so far ... you have to be a little conscious about poking a hole in it.  I've not had that problem, but I know my paddling partner's "sprung a leak" on one trip.  He has also used his as a shower on a trip or two.

    I fought with claening disinfecting and drying collapsable water containers my self. However I have found a reasonable solution that works well for me. I use a solution of 2 tablespoons of household bleach per liter of water to clean and disinfect my water containers and filters after a trip including water bottles. I have never noticed a plastic taste, but then again my wife would tell you I have no taste buds anyway. The baking soda would work well after you hae the container disinfected and dry.

  I really like Denton Docs water container idea. Easy to clean and dry after usage for sure. These guys are the camping masters.

We use these water bags:   (You need to Login or Register to view media files and links)

Quick filling, large capacity, easy to clean, will not spill too much in the bottom of the canoe, hang easily, and double as a solar shower.  Since they pack small, we put them in an easily accessible area and get our water away from shore before arriving in camp.  2 bags are usually enough for a crew of 6 for an overnight stay, unless they are used for showers.

More good ideas, thanks again.
