Cheyenne River is the Good River Reservation

We welcome you to the Cheyenne River Sioux Reservation—the Good River Reservation or Wakpa Wasté Oyanke. Rich in history and culture, Cheyenne River is home to great Native American leaders, world champion cowboys, abundant wildlife, fresh air, and wide open spaces. Here you’ll have the opportunity to enjoy local hospitality, western history, and Lakota culture.

Finding Your Way Around

There are 27 communities throughout the Reservation, but four towns serve the greater population. Isabel, Dupree, Eagle Butte and Timber Lake provide products, recreational opportunities, medical and educational facilities, churches, financial services, lodging and dining establishments.

Take a Drive

Two nationally recognized drives are found on the Reservation; the Native American Scenic Byway and the Lewis and Clark Trail. Both routes provide a scenic and historic tour for visitors. BIA (Bureau of Indian Affairs) roads are mostly gravel and are in good condition for traveling with a four wheel drive vehicle.

Featured Communities

The Cheyenne River Sioux Reservation is a vast area where one can enjoy what seems like never-ending open spaces of rolling prairie. In between the areas of sprawling untouched nature, are rural towns where one can find small shops and places to eat.


The community of Dupree is located on the west end of the Cheyenne River Reservation, along Hwy. 212. This western community plays host to numerous events each year, including the regional high school rodeo held the 2nd weekend in June, and the Pioneer Days Celebration held the second weekend in July.

Eagle Butte

Eagle Butte, founded in 1910, serves as the headquarters for the Cheyenne River Sioux Tribe. Every year, the Tribe’s annual Fair and Powwow is held in Eagle Butte over Labor Day weekend, in September. Located along Hwy 212, in the central portion of the Reservation, the community boasts a variety of products and services for area consumers. The Eagle Butte Community Club puts on the Hometown Days celebration every July.


Founded in 1911, the town of Isabel is located in the northern portion of the Cheyenne River Reservation. In the early years, the railroad played an important role in the establishment of the community. Today, agriculture is the leading industry. Each year, the town hosts a celebration and rodeo the first weekend in August.

Timber Lake

Timber Lake was founded in 1910 when the Cheyenne River Sioux Reservation was opened to homesteading. Livestock and grain provide the base for the local economy, which also includes small manufacturing, recreation, and home-based businesses. Timber Lake’s Days of 1910 Celebration is held annually the last full weekend in July.
