Sioux County, then east through
Agate Fossil Beds National Monument, past Marsland, and through Box Butte Reservoir. It flows east across northern Nebraska, near the north edge of the
Sandhills, past
Valentine. It is joined by the
Snake River about 13 mi (21 km) southwest of Valentine. In north-central Nebraska it is joined by the
Keya Paha River approximately 6 mi (10 km) west of

Perhaps the epitome of a prairie river, the Niobrara is known as a biological crossroads. Although traversing primarily private land, it also flows by the Fort Niobrara National Wildlife Refuge and the largest single holding of The Nature Conservancy where bison have been reintroduced. The upper portion provides excellent canoeing below Valentine.
