Description, Use and Regulations

Description:  The Tyson Bend site is located along the left descending bank of the Missouri River. A large backwater and a portion of an off-channel chute were constructed at Tyson Bend. Connection of the upstream portion of the backwater area/chute to the Missouri River was not completed due to unavailable real estate on the upstream portion of the project.

  • The chute, which is currently functioning as a portion of the backwater is 13,500 feet in length, exits on the downstream side of the project and includes a rock separation dike and an outlet dike revision to reduce backwater sediment deposition.
  • Removal of the deposited material at the backwater entrance was performed to allow river connection at normal flows.
  • The project will create approximately 44 acres of shallow water habitat for the chute and 71 acres at the backwater.

Status:  Open to the public. Channel repair is planned. Site/Habitat is in operations and maintenance status.

Site Use:  The site is open to the public for a variety of outdoor activities including fishing, bird watching, hiking and hunting (under special regulations).
