To help identify Management Unit boundaries, a few major ports are listed for each. The map on Great Lakes Trout & Splake Regulations provides a graphic to further define the boundaries. For a complete description of lake trout Management Unit boundaries, contact any DNR Customer Service Center or check online at michigan.gov/dnr.
Anglers and boaters on the Great Lakes may encounter commercial fishing gear such as trap nets, gill nets and set hooks in Michigan waters. All state-licensed or Native American commercial fishing gear are required to be marked with floats or staff/flag buoy combinations depending on the licensing entity. Anglers and boaters should give wide berth to any markers, since anchor lines may extend several hundred feet in any direction from the floats or flags along the length of the gear. The diagrams to the right will give sport anglers and boaters an idea about some of the markings they might encounter and assist them in avoiding entanglement of fishing gear or boat propellers. Tampering with commercial fishing gear is illegal and can create safety problems for other boaters on the water.
