"Considered to be one of the few significant trout streams in Central Montana, Big Spring Creek is the third largest freshwater spring in the world and bubbles to the earth’s surface in the foothills between the Judith and Big Snowy Mountains. The cold water is quickly absorbed back into the porous strata and reemerges again at Big Spring flowing at over 50,000 gallons per minute. Once a sacred site to Native Americans, and later a valuable resource to early settlers, Big Spring Creek is still a prized water source.

Big Spring water is also bottled and shipped across the country under a variety of labels. Types of Fish: Rainbow and Brown Trout, Whitefish.
