For various reasons, largely social, numerous stocking associations are engaged in attempts to manage the lake's walleye population.

The river has an important native walleye population that has stabilized in recent years.

An average of one yellow perch was caught per net, but surveys failed to find any presence of the walleye population which state fisheries had been trying to establish in the lake through three years of fry stocking.

Below the dam from Lake Menomin the Red Cedar river is well known for its large walleye population.

Many feel the increased population of muskies has had a detrimental effect on the walleye population; most notably in the western basin.

This limits the size of the walleye population, although once they grow large enough they can forage on Brule's much larger cisco population.

Anglers are attracted to the stocked walleye population in Gull Lake.

There are occasional reports of blue walleye being caught from waters in the Great Lakes Basin, because many yellow walleye populations also contain a colour variant with a bluish colour.

But today many Canadian lodge owners cite studies by Canadian biologists to show that some of the lake's walleye populations are Maple Leaf nationalists from gills to tails, rarely venturing into American waters, where there are few sheltering islands.
