Kannah Creek is a watershed that descends from the top of the Grand Mesa west southwest, where it meets the Gunnison River about 25 miles south of Grand Junction, Colorado. It offers many recreational opportunities, irrigation, and is an important source of drinking water for Grand Junction. The Grand Mesa is one of the largest flat topped mountains in the world and has over 300 lakes and reservoirs on top, many of which are in the Kannah Creek watershed, which help retain much of Grand Junction's drinking water throughout the year as the snowpack melts and converts into runoff. Kannah Creek is also the namesake for the locally popular Kannah Creek Brewing Company. Kannah Creek is an extremely important source of water, originating on an elevated oasis, in an otherwise very arid region.
