Features

Lakes Poygan, Winneconne, and Butte des Morts are the “upriver lakes” of the vast Winnebago system. These “upriver lakes” cover 27,466 acres. The annual spring runs of walleye and white bass are infamous nationwide and draw thousands of anglers. These large, shallow lakes can become quite rough in windy conditions. Constant monitoring of weather conditions is advisable for anglers especially those with small boats. Navigation in off-channel areas of Lake Butte des Morts can be hazardous for larger boats due to shallow water areas and unmarked rock piles. Pay close attention to marker buoys which point out navigational routes.

Forage

Juvenile carp, redhorse, white sucker, golden shiner, emerald shiner, spottail shiner, log perch, trout perch and juvenile panfish are key species in an abundant forage base. Gizzard shad are significant although they tend to cyclically die-off and reemerge. Crayfish are also present. Aquatic insect hatches also have a great impact on the forage base.

Seasonal Movements

Lake Butte des Morts receives the entire run of Lake Winnebago walleye as they migrate up the Fox or Wolf Rivers. There is a tendency for spawning walleye to return to the same area, or at least their natal river, year after year. Lake Poygan walleye begin their upstream movement approximately one to two weeks before walleye move up from Lake Winnebago. In an average year, the walleye migration will be completed during the month of April. The Winneconne walleye movement up the Wolf River occurs after the Poygan movement because Winneconne lacks tributary streams flowing into it. Winneconne harbors a tremendous influx of walleye as they move up from Lake Winnebago. A significant number of white bass move through Lake Winneconne during the months of April and May. From June through August, white bass are loosely schooled in the open-water basins of the lake. Tighter schools are formed in the fall. The white bass migration through Poygan lasts the entire month of May.
