We HIGHLY discourage you from filtering/boiling/using tablets with the water from the Wisconsin River - keep in mind it's draining 1/3 of the Dairy State (we also are the 16th largest producer of hogs).  We also believe purchasing single serving plastic water bottles produces too much trash. We recommend purchasing large jugs of water, or using a water tank of sorts, and simply filling personal water bottles as needed. There are a few options for filling water jugs during your trip. This is the safest way to go about providing drinking and cooking water for your group. See our list of boat landings and their amenities.
