General/Marine Construction (Excluding Bridges)/Dredging Mariners are advised that The King Company, Inc. will be conducting hydraulic dredging operations in the Caseville Federal Channel, Michigan from September 21, 2026 through November 15, 2026. The dredge “Buxton II” will operate 24 hours per day, 7 days a week (weather permitting). Submerged dredge pipe will be lying on the lake floor and will be marked by orange round buoys every 1,000 feet. Two white buoys will be visible north and south of the dredge marking winch anchor locations. The dredge disposal area begins 13,728 feet west of the channel and extends an additional 3,350 feet westward. Material will be placed between the Ordinary High Water Mark (beach) and the 4-foot depth contour. The disposal area will be marked with white buoys on each corner. During rough seas, a bright yellow pipe pontoon measuring 25’ x 8’ x 6’ with two flashing amber lights on each end will be floating outside of the channel. A second identical bright yellow pipe pontoon with two flashing amber lights will be located in the disposal area. Mariners are requested to avoid the dredge, all pipelines, buoys, anchors, and pontoons, maintain a safe distance, reduce wake, and proceed with caution. The main point of contact is Superintendent Joseph Martin. For emergencies or questions, contact the main office at (616) 399-1784 or Superintendent Martin directly at (941) 628-6783.
