Two corners
Lake Superior is the coldest, deepest and least productive of the
Great Lakes. That is good for lake trout and bad for yellow perch.
Perch need warm, shallow, weedy water. Superior has very little of it.
What it does have is two corners on the south and west shores that behave more like
inland lakes than like Superior. One is Chequamegon Bay at Ashland and Washburn. The
other is the St. Louis River estuary between Superior and Duluth. Wisconsin DNR
names those two as the most productive perch water on the lake. Outside them, you
will not find a perch fishery.
On size: if a pail of 12-inch jumbos is the
goal, Lake Erie is the better trip. Superior perch are a
winter mixed bag, fished on the ice by people who are often after walleye, pike or
trout too.
Chequamegon Bay
Chequamegon Bay covers about 34,000 acres behind Long Island and the Apostle
Islands, with a mean depth of 28 feet. It is shallow, productive and protected from
high-efficiency commercial gear. That is why it carries a year-round sport fishery
for walleye, smallmouth, pike and perch that the open lake cannot.
Ice anglers follow the forming ice along the main shore from Ashland toward
Houghton Point. The DNR’s fishing calendar names the landings off Ashland and the
water off the Washburn and Bayfield marinas as productive January perch spots, with
perch and walleye picking up again off Ashland and Washburn in March. In summer,
recent DNR reports put the perch around the deeper weed beds.
What the survey nets say
Wisconsin DNR has run a standard fall gill-net survey in the bay since 2019. In
2024, perch were among the most numerous fish in the nets. Most were
between 6 and 11 inches, with a median of 6.9. Abundance climbed from a 2019 low to
a 2021 high as a strong group of young fish came in. It has eased slightly since,
and the average fish has gotten bigger.
The longer record is more mixed. The DNR’s Lake Superior management plan reports
that perch catch rates in the bay’s ice fishery have fallen over 25 years while
harvest held fairly steady and growth improved. Walleye stocking off the Ashland
shoreline began partly to thin out what managers suspected was a stunted perch
population and improve its size structure. White perch numbers in the bay have
also climbed sharply since 2019. Fishery biologists are watching that.
The St. Louis River estuary
The St. Louis River widens into a big, shallow estuary behind Minnesota Point and
Wisconsin Point before it reaches the lake. It is best known for walleye and muskie.
Perch are year-round residents, and Wisconsin DNR names the estuary alongside
Chequamegon Bay as the lake’s main perch water. Creel data cited in the DNR’s plan
shows perch catch rates falling from 1989 to 2015, even as the share of anglers fishing for them held
steady.
Fish the protected side bays off the main channel, such as Pokegama Bay. Expect
perch mixed in with crappie, sunfish, pike and walleye. Launch from Barkers Island
in Superior and stay out of the shipping lanes. The harbor runs ore boats and
lakers.
How to fish them
On the ice, use small spoons and jigging minnows tipped with a minnow head or
waxworms. Work them with short lifts and long pauses on light line, and watch a
flasher. Move when a hole dies. A deadstick minnow set beside the jigging hole picks
off the fish that follow the spoon but won’t hit it. In June, anchor on the outside
edge of the deeper weeds and fish a spreader rig. In the estuary, go smaller: a tiny
jig and a couple of spikes, held still just off the bottom.
The bay is still Superior
Chequamegon Bay freezes earlier and more reliably than the open lake, but it is
still Lake Superior water. Ice conditions change with wind and current, especially
near the bay mouth, near river mouths and on the estuary’s channels. Check with
local bait shops before you go out. Carry picks and a spud, and read the
Great Lakes ice safety guide before
your first trip. While you’re in town, the same bay also produces
pike and whitefish.
Regulations
Wisconsin DNR manages Chequamegon Bay and the rest of Wisconsin’s Lake Superior
waters. The St. Louis River estuary is a boundary water shared by Wisconsin and
Minnesota DNR, with its own rules. Perch seasons and limits differ between these
waters and change. Read the current regulations from the agency whose water you’re
on before you fish.
