About the Yellowstone River

The Yellowstone River stretches over 670 miles and is the longest free-flowing river in the lower 48 states. Originating in Yellowstone National Park, it drains 70,000 square miles of land before it joins the Missouri River northeast of Sidney, Montana. In addition to an abundance of fish and wildlife, the Yellowstone River supports a wide variety of agricultural, domestic, industrial, and recreational uses.

About Us

The Yellowstone River Conservation Districts Council (YRCDC) is comprised of eleven member districts along the main stem of the Yellowstone River. Our purpose is to provide local leadership, assistance, and guidance for the wise use and conservation of the Yellowstone River’s natural resources. This purpose is founded on three fundamental precepts:

1) The need for scientific information on which to base management decisions.

2) The need for broad-based local, regional, and national input.

3) The need for technical and financial assistance to address sustainable use issues on the Yellowstone River.
