They can be found living near the top of the thermocline where water temperatures approach 69 degrees. Depending on the lake, this depth will usually be somewhere between 12 and 18 feet.
To locate this depth, either use a lake thermometer (available at most larger tackle stores) or contact the nearest DNR office.
If the lake has a public access site, fisheries biologists will have surveyed it and will have a temperature – oxygen profile of the lake.
This chart will identify the depth with a temperature near 69 degrees.
Try fishing at this depth where the 69 degree temperature is close to the bottom…usually at the deep edge of weed beds.
Use light line (four-pound test or less) tipped with a white ice-fishing tear-drop jig baited with a wax worm.
Some anglers use slip bobbers, while others fish European-style with very long fiberglass poles. Early morning and dusk are most productive.
