Minnesota is walleye country and Mille Lacs is its cathedral: 132,000 acres of gravel reefs and legendary offshore mud flats, plus a trophy smallmouth fishery that snuck up on the whole country and a winter ice-house city that has to be seen.

Live verdicts from this morning's reports.
Minnesota's walleye legend: 132,000 acres of reefs, mud flats and the state's most storied ice fishery.
Minnesota's third-largest: walleye reefs, muskie legend and Chippewa National Forest wild.
Lake of the Woods: a Canada-Minnesota border water with its own walleye, sauger and northern pike limits, and two Minnesota state-record fish.
Lake Vermilion: a 365-island St. Louis County lake under its own 20-26-inch walleye protected slot.
Cass Lake: the largest lake of the Cass Lake Chain in the Chippewa National Forest, fished for walleye, northern pike, perch and muskie.
Big Winnie: the walleye factory where wind decides everything.
Lake Pepin: a natural 29,295-acre lake on the Mississippi River, formed behind the Chippewa River's delta and fished under Minnesota-Wisconsin border-water rules.
Rainy Lake: a 227,604-acre Minnesota–Ontario border lake, a third of it inside Voyageurs National Park, fished under Minnesota's Rainy Lake walleye rule.
The prairie border lake: 26 miles of Minnesota-South Dakota water at the Minnesota River's source, grinding out walleye and perch the old way.
Minnesota's driftless jewel: limestone spring creeks braiding through bluff country, thick with wild browns and bikeable access.
The Twin Cities' trophy maze: 14,000 acres of bays and channels where metro muskies, bragging-size bass and ice culture share the docks.
Brainerd's flagship: the resort-country classic where Minnesota learned to fish walleye chop over gravel and muskies haunt the cabbage.
The comeback of comebacks: tribal-state cooperation resurrected Red Lake's walleye, and the ice city that followed became Minnesota legend.
Minnesota's two-story secret: a 60-foot glacial bowl stocked with lake trout, browns and the clarity to sight-fish them all.
Lake Waconia: a 3,080-acre Carver County lake with a special walleye size rule and a stocked muskellunge population.
Lake Bemidji: the Mississippi River's lake at Bemidji, crossed by the state water trail between Paul Bunyan City Park and Lake Bemidji State Park.
Green Lake at Spicer: Kandiyohi County's largest and deepest lake, about 5,400 acres and 110 feet at its deepest, with a special 3-walleye possession limit.
A 25,760-acre lake entirely inside Voyageurs National Park, fished under Minnesota's 18–26-inch protected walleye slot.

Minnesota's identity is walleye: Mille Lacs, Leech, Winnibigoshish and the border waters (Rainy, Lake of the Woods) form the sport's American heartland. But the state is deeper than its state fish: trophy muskies in the metro lakes, smallmouth rivers (the Mississippi's upper pools are superb), stream trout in the southeast's driftless valleys, and a north-country canoe wilderness where every portage hides pike and lake trout.
The mid-May walleye opener is a cultural holiday. June: everything active, bugs included. Summer: mud-flat walleye on Mille Lacs, muskie hunts, evening hex hatches. Fall: the big-fish window: reefs at dusk, muskies feeding down. Then the long season: Minnesota ice fishing is a way of life, with wheelhouse cities on every major lake from December to March.
Rules are set season by season under state-tribal management: some years catch-and-release, some a narrow slot. Always check current MDNR regulations: the rules on the day you fish are what count.
