260,338-acre section. The western tip off Duluth and Superior: kamloops and coho close to shore, lake trout on the shipping-lane drops and walleye out of the St. Louis estuary.
602,417-acre section. Island-studded lake trout water off Bayfield, and shallow Chequamegon Bay with its famous smallmouth and brown trout fishery out of Ashland.
769,701-acre section. Keweenaw Bay to Copper Harbor: the deepest, wildest water on the American side. Lake trout everywhere and coaster brook trout along the rocky shore.
521,274-acre section. Marquette to Munising and Grand Island: spring coho along the beaches, lake trout on the humps and steelhead off every river mouth.

78,843-acre section. Batchawana Bay on Lake Superior's eastern shore northwest of Sault Ste. Marie — a river-fed bay with walleye, northern pike and smallmouth in its warmer water, and lake trout, chinook and coho salmon, steelhead and coaster brook trout out on the big lake.
The released set contains 5 survey-backed sections and 0 modeled sections. Their published maximum depths run from 275 to 850 ft, with a median of 756 ft. Those numbers make scale differences visible, but they do not make sections interchangeable: contour provenance, access, species evidence and local structure remain specific to each child map.
Start with the section closest to the water you actually plan to fish. Then compare its depth-data label and species roster with an adjacent section before treating a pattern as system-wide. A survey-backed child is the stronger choice for precise breakline planning; a modeled child is broader reconnaissance and should be checked against sonar and conditions on the water. Return to this overview whenever you cross into another mapped reach, pool or coastal section.
Same child-page contract
What every section keeps separate
Depth provenance: each child discloses whether its contours are survey-backed or modeled; a family card never upgrades that label.
Fishing spots: structure and seasonal recommendations are calculated inside the child boundary so distant reaches are not mixed together.
Fish species: each page keeps its own supported roster rather than inheriting every species found anywhere in the parent system.
Local context: hatch guidance, access, hazards, catches and nearby-water links continue to resolve for the individual child where data is available.
Planning questions
Frequently asked questions
Why is Lake Superior divided into separate fishing maps?
Long travel distances and locally distinct bays, island shelves and exposed shores make one lake-wide fishing page impractical.
Are these depth maps survey-backed?
5 released maps use surveyed or official agency bathymetry. Each child keeps its own provider, product, datum and not-for-navigation disclosure.
Do fish and access records apply everywhere?
No. Species, forage, access and fishing spots remain scoped to each child map and retain their evidence labels.
