  1. 1. Installation and Evaluation of Fish Habitat Structures in Bull Shoals Lake, Missouri Dylan Bussell Fisheries Biologist Missouri Department of Conservation
  2. 2. Project Area • Bull Shoals Lake: – 48,000 acre reservoir located on the White River, built in 1951 • Norfork Lake: – 22,000 acre reservoir located on the North Fork of the White River, built in 1944 • Both are owned and operated by the U.S. Army Corps of Engineers • Both are situated partially in Missouri and Arkansas • Missouri Department of Conservation and Arkansas Game and Fish Commission are primarily responsible for fisheries management activities
  3. 3. Project Outline • Increase fish habitat structure in the Missouri portions of Bull Shoals Lake and Norfork Lake. – Approval from the U.S. Army Corps of Engineers to place fish habitat structures in the lake – Hire staff and contractors – Fabricate anchors – Select, cut, and drag trees to shoreline – Attach anchors and sink trees – Functional design of fish habitat structures – Stakeholder engagement – Evaluation of fish habitat structures
  4. 4. U.S. Army Corps of Engineers Approval
  5. 5. Hire Staff and Contractors • MDC Hired Temporary Staff: – Fisheries Biologist- Coordinates and Implements project – Resource Assistant- Assists Fisheries Biologist with project implementation • MDC Contracted: – Two Laborers- Cut cedar trees, attach drag ropes to trees, and attach anchors to trees
  6. 6. Anchor Fabrication
  7. 7. Tree Selection and Cutting • Live trees are easier to sink • Full Crown with many large diameter limbs • Average 10 inches diameter at breast height
  8. 8. Dragging Trees to the Shoreline
  9. 9. Attaching Anchors
  10. 10. Sinking Trees
  11. 11. Structure Design • Elongated structures perpendicular to shoreline – Extend 10’ to 30’ deep in coves – Extend 20’ to 40’ deep in main lake areas • Facilitates angler accessibility and sportfish use with the constraints of a fluctuating water level. • Each fish habitat structure is made of at least 4 to 8 cedar trees • Each tree averages 5 anchors (approximately 400 lbs.)
  12. 12. Stakeholder Engagement • Advertisements through MDC Website, Newspapers, and Social Media.
  13. 13. Stakeholder Engagement
  14. 14. Evaluation of Structures • Evaluation of fish habitat structures: – Angler use – Fish use – Structure longevity – Structure design
  15. 15. Sponsors
