With 671 miles of flowing water, the Yellowstone River is the last major undammed river in the lower 48 states. This marvelous stretch of water begins through the Absaroka Mountain Ranges, flowing into Yellowstone National Park and entering the park’s lake. It then peacefully makes its way through Hayden Valley before colliding with the upper and lower falls of the Grand Canyon. The Yellowstone River returns to Lamar Valley before leaving the park in Gardiner, Montana. The river joins the Missouri River, then combines with the Mississippi River before heading into the Atlantic Ocean. 

The Yellowstone River is considered a primary resource in the district because it provides grizzly bears with critical food sources in the spring. It is vital to the surrounding ecosystem; however, floodplain development threatens the river's health and sustainability. Dam construction could severely prevent native fish species from being able to travel through the river, eventually damaging the structure of the local ecosystem. It is important that this essential river stays protected and continues to provide its surrounding habitats. 

Besides kayaking, floating, rafting or just old fun swimming there's many things to enjoy about the Yellowstone River. The river is a  major destination, with over 100 miles of blue ribbon river for beginner to expert fly fishermen to actively fish for wild trout!
