Generally, near-shore water temperatures will be too warm to host trout or salmon. Fishing during this period takes place in deeper water with Lake Trout being the most commonly targeted fish. Trolling (dragging lures behind a boat) is probably the most popular and successful method of catching trout and salmon in the Apostle Islands. A very popular and productive 'sportfishing only' area has been established by the Wisconsin Department of Natural Resources between Madeline and Long Islands. The area around Sand and Eagle Islands, or out near Cat Island can also yield successful results. Fishermen should not approach within 500 feet of Eagle Island during this period so as not to disturb colonies of nesting birds on the island.
