Bad River (South Dakota)


The Bad River is a tributary of the Missouri River, approximately long, in central South Dakota in the United States.
The river is formed at Philip, South Dakota, by the confluence of its North and South forks. The North Fork Bad River rises in eastern Pennington County and flows east-southeast to Philip, while the South Fork Bad River rises at the confluence of Whitewater Creek and Big Buffalo Creek in Jackson County, within the Buffalo Gap National Grassland, and flows northeast to Philip. The main stem of the Bad River flows east-northeast from Philip, passing Midland and Capa. It joins the Missouri at Fort Pierre. The Bad drainage basin is about and is located south of the Cheyenne River in the Pierre Hills and Southern Plateaus.
The river basin is noted for deposits of manganese and fuller's earth. At the river mouth near Fort Pierre, the Bad River flood stage contains large quantities of silt. The Bad carries hard water of generally poor quality.
The name recalls an incident when a flash flood on the Bad River inundated an Indian village, causing a large loss of life. The Bad River is also historically known as the Teton River.

Industrial use

As of November 2019, TC Energy was applying for permits in the state to tap the Bad River to use water for the construction of Phase 4 of the Keystone pipeline, including camp construction to house transient construction workers.
