Authorities recovered two bodies this week near a washed-out section of road on the Standing Rock Reservation.

The Bismarck Tribune reports the two fatalities have been identified as Trudy Peterson, an Indian Health Service nurse from Mobridge, and Jim Vanderwal, a mail carrier.

Authorities say they also rescued two drivers from floodwaters early Tuesday.on BIA Road 3 (part of Highway 1806) south of the North Dakota-South Dakota line.

The Burleigh County Sheriff's Department says a swiftwater rescue team, a dive team and a drone operator from Burleigh County were involved in the search-and-rescue mission downstate.

A tribal spokesperson says emergency personnel airlifted one survivor, the driver of a Sitting Bull College bus, to a Bismarck hospital. The other, a tribal worker rescued from the back of his pickup, went to Mobridge Regional Hospital and later to Bismarck.

The survivors' names were not immediately released.

Sioux County Sheriff Frank Landeis says the stretch of road could be closed up to a week.
