How to Catch Stream Trout in Minnesota Lakes: Rainbows, Brookies, Browns & Splake

Minnesota manages well over a hundred small, cold lakes and flooded mine pits as designated stream trout lakes, stocking them with rainbow trout, brook trout, brown trout and splake. They are put-and-take or put-grow-and-take fisheries, and they fish best in the first weeks after the mid-May opener and again at first ice in January. You need a trout and salmon stamp, you may use only one line, and live minnows are not allowed. The 2026 limit is 5 trout combined with no more than 3 over 16 inches.

The four fish

Species	How to tell	Notes
Rainbow trout	Pink to red stripe along the side, small black spots covering the body and the whole tail	The most widely stocked. Cruises open water and feeds near the surface.
Brook trout	Worm-like markings on the back, red spots with blue halos, white-edged lower fins, nearly square tail	Minnesota's native stream trout. Stays close to shore, wood and shallow structure.
Brown trout	Golden-brown body, black and red-orange spots with pale halos, few or no spots on the tail	Wary, tolerates slightly warmer water, feeds heavily at low light.
Splake	Looks like a pale brook trout with a slightly forked tail	Lake trout and brook trout hybrid. Roams deeper and is an ice-fishing favorite.

All four need cold, oxygenated water, so in midsummer they hold at or just above the thermocline rather than in the warm shallows.

Where these lakes are

The DNR publishes a searchable map and list of designated trout lakes, and the legal list sits in Minnesota Rules 6264.0050. A lake is only a designated trout lake if it is on that list. The main clusters:

• Arrowhead. The largest concentration by far is in Cook, Lake and St. Louis counties: small lakes off the Gunflint Trail, the Sawbill and Caribou trails and around Ely, some drive-up and some inside the Boundary Waters. Tofte Lake and Miners Lake at Ely are well-known examples. See /lakes/cook-county and /lakes/lake-county.
• Mine pits. Deep, clear, cold pit lakes on the Cuyuna Range near Crosby and Ironton and on the Mesabi Range are natural trout water once stocked. Shorelines are steep and shore access can be limited. See mine pit lakes of the Cuyuna and Iron Range.
• North-central. Scattered small lakes in Itasca, Cass, Hubbard, Beltrami and Aitkin counties. Larson Lake in Itasca County produced the state record splake.
• Twin Cities. A handful of small metro lakes and ponds are designated and stocked, including Courthouse Lake in Chaska, Cenaiko Lake in Coon Rapids and Quarry Lake in Scott County, giving metro anglers a trout option without a long drive. See fishing near Minneapolis.

Stocking varies year to year and lake to lake. Check the stocking report on the DNR LakeFinder page for a lake before you go, and see /fishing/stocked and Minnesota fish stocking explained.

Season by season

• Opener through early June. Cold water top to bottom. Trout cruise the shallows and the surface, and shore anglers do as well as boats. This is the best open-water window.
• Mid-June through August. Surface water warms and fish drop to the thermocline, often 15 to 30 feet down over deeper water. Early morning and dusk bring some back up to feed on hatching insects. Midday fishing is slow.
• September and October. Cooling water brings trout shallow again. Brook trout and splake color up. The lake season stays open through October 31, a month longer than lake trout.
• November and December. Closed. No fishing of any kind on designated trout lakes.
• Mid-January through March. The winter opener is a minor holiday in the Arrowhead and on the Cuyuna pits. Fish are shallow, often 5 to 15 feet along shorelines for brook trout and rainbows, deeper for splake. Action is best the first two weeks and tapers as lakes get fished down.

Techniques and rigs

Open water

• Slip bobber and bait. A small hook, a split shot and a piece of nightcrawler or a waxworm set at the depth fish are holding. Simple and reliable, especially from shore.
• Floating dough bait on the bottom. A sliding sinker, an 18 to 24 inch leader and a floating bait that rides up off the bottom catches recently stocked rainbows.
• Small spoons and spinners. Cast or troll slowly from a canoe. In summer, add weight or use a small diving lure to reach the thermocline.
• Flies. A float tube and a sinking line with a leech pattern or small streamer is deadly on small trout lakes. When fish are rising at dusk, a dry fly or an emerger works.

Ice

• Fish shallow first. Brook trout and rainbows patrol shoreline logs, points and inlets in a few feet of water. Drill your holes quietly, early, and then stay off them for a while.
• Jig a small spoon or tungsten jig tipped with a waxworm, or hang a waxworm or a preserved minnow under a float.
• In clear, shallow water, sight-fishing from a dark shelter lets you watch trout come in.
• Splake respond to more aggressive jigging and are often a bit deeper, 15 to 30 feet.
• Remember you get one line, not the two allowed on most Minnesota lakes in winter.

Gear

• Light or ultralight spinning rod, 5.5 to 7 feet, with 4 pound line. Trout in clear lakes and pits shy from heavy line; a 4 pound fluorocarbon leader helps.
• Hooks size 8 to 12, small split shot, slip bobbers.
• A canoe, kayak or float tube opens up most of these lakes. Many have carry-in access only and no ramp. See /fishing/easy-access and /paddling.
• For ice: a light 24 to 28 inch rod, 3 to 4 pound line, and a hand auger. Many trout lakes are walk-in.

Regulations for stream trout lakes, 2026-27

Verified against the 2026 Minnesota DNR fishing regulations, effective March 1, 2026 through February 28, 2027:

Season	Dates	Limit
Summer, statewide lakes	May 9 to October 31, 2026	5 combined, not more than 3 over 16 inches
Winter, lakes outside or partly outside the BWCAW	January 16 to March 31, 2027 (2026: January 17 to March 31)	Same
Winter, lakes entirely within the BWCAW	January 1 to March 31, 2027	Same

Rules specific to designated stream trout lakes:

• Trout and salmon stamp required to fish them at all, with exemptions for anglers under 18, 65 and older, and those on 24-hour or 72-hour licenses. It was 10 dollars in 2026. See Minnesota fishing license.
• One line per angler, summer and winter.
• No live minnows in possession or as bait. Preserved minnows, leeches, worms and waxworms are fine.
• Fishing hours for stream trout on inland waters are one hour before sunrise to 11 p.m.
• Closed means closed to everything. No fishing for any species outside the trout season.
• Winter closures. The 2026 book lists four lakes with no winter stream trout season: Little Andrus (Snowshoe) in Cass County, Allen and Pleasant in Crow Wing County, and Bad Medicine in Becker County.
• Transport trout with head, tail, fins and skin intact.

Trout streams follow different dates and a different size rule (5 combined with only 1 over 16 inches in 2026), and Lake Superior and its tributaries have their own table. This guide covers lakes only. Regulations change yearly; confirm with the DNR.

State records

From the DNR state record fish lists:

• Splake: 13 pounds 5 ounces, Larson Lake, Itasca County, February 2001.
• Brook trout: 6 pounds 5 ounces, Pigeon River, Cook County, 2000.
• Brown trout: 16 pounds 12 ounces, Lake Superior, St. Louis County, 1989.
• Rainbow trout (steelhead): 16 pounds 6 ounces, Devil Track River, Cook County, 1980.

Note that the brown and rainbow records came from Lake Superior and its tributaries, not from stocked inland lakes, where a 3-pound trout is a very good fish.

Handling and release

• Trout are fragile. Wet your hands, keep the fish in the water and skip the dry towel or glove.
• Warm surface water in July and August is hard on released trout. If you are fishing in midsummer, plan to keep what you catch within the limit.
• Bait-caught trout often swallow the hook. Cut the line rather than digging, or keep the fish.
• These are stocked fisheries managed for harvest. Keeping a limit of eating-sized trout is what they are for; releasing the occasional large holdover keeps a few big fish in the lake.

Before you go

• Confirm the lake is on the DNR designated trout lake list and check its recent stocking.
• Buy the trout stamp, bring one rod per person and leave the minnow bucket at home.
• Go early: the first two weeks of the May and January seasons are far better than the rest.
