Target species

Species from state lake data, resolved by location. These species come from the Wisconsin DNR's own per-lake fish listing. Where the DNR reports a group rather than a species — “panfish”, “catfish”, “trout” — the specific species are resolved from Wisconsin's fish distribution by this lake's location, depth and habitat, so those are an informed estimate, not a per-species survey. The named gamefish (walleye, musky, bass, pike, sturgeon…) are the DNR's own listing. (The depth chart is a computer-generated estimate from the lake's real shoreline and the DNR's maximum depth — not measured contours.) How we estimate species →

Hatch outlook

Fall shiner runActive window

Typical here: Sep 1 – Oct 31 · colder nights and shortening days start the push in early September — shiners slide out of open water toward warmer shallows and run up the rivers; the Rainy River run off Lake of the Woods is the marquee version

adultdaylight for the jig bite; after dark the shiners stack under dock lights with walleyes and pike mixed right in — follow the bait, not the spot — millions of shiners move together and the predators ride with them; silver profile and flash matter

Concentrates hard but travels — the school (and the walleyes under it) can be off a river mouth one week and miles upriver the next.

Jig-and-minnow is the event's signature — a frozen emerald shiner on a 1/4 oz jig drifted along the run; silver jerkbaits and trolled crankbaits take the roaming fish; blade baits under the schools.

The event happens over river mouths and the first miles upriver, warming shallow shorelines, and rocky points where the displaced bait stacks

Fishing T Lake: what the data says

13-acre lake in Polk County, Wisconsin. The lake tops out around 45 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. What the data behind the map says about each species, season by season:

Drawn out, this is 13 acres of water rimmed by 0.9 miles of bank. Index 1.8 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 32% of this chart, as modeled. The water lies in Polk County. Closest neighbour on DepthScout: Twin Lake, 0 mi south of here.

Yellow Perch fishing at T Lake

Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 15 to 35 ft. Put Deep basin first on the milk run — a deep basin near 38 ft that grades prime for fall. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 12 ft	midday & dawn	open water	Small jig + curly tail, Perch-pattern micro crank
Summer	10 to 30 ft	dawn	Deep basin (38 ft)	Drop-shot micro plastics, Small spoon tipped with worm
Fall	12 to 35 ft	midday	Deep basin (38 ft)	Jigging spoon (small), Perch rig / spreader
Winter	15 to 35 ft	midday & dawn	Deep basin (38 ft)	Tungsten jig + spikes, Rattle spoon (small)

Largemouth Bass fishing at T Lake

Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Fall largemouth bass concentrate at Main-lake point, a prime-rated point around 11 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 10 ft	dawn & dusk	Main-lake point (11 ft)	Spinnerbait, Chatterbait
Summer	8 to 20 ft	dawn & dusk	Main-lake point (11 ft)	Texas-rigged 10" worm, Deep-diving crankbait
Fall	4 to 15 ft	midday & dawn	Main-lake point (11 ft)	Squarebill crankbait (shad), Spinnerbait
Winter	15 to 35 ft	midday	Deep basin (38 ft)	Blade bait, Jigging spoon

Crappie fishing at T Lake

In spring, crappie run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 10 to 25 ft, and winter fish settle into 15 to 35 ft. Deep basin is the standout, a deep basin at roughly 38 ft, rated prime for winter crappie. Time it for early morning and the evening. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 8 ft	midday & dawn	open water	1/16 oz jig + tube, Curly-tail grub
Summer	10 to 25 ft	dawn & dusk	open water	Jig trolled/spider-rigged, Small crankbait (trolled)
Fall	8 to 20 ft	dawn	open water	Jig + minnow combo, Small swimbait (1.5-2")
Winter	15 to 35 ft	midday	Deep basin (38 ft)	Tungsten jig + soft plastic, Tiny jigging spoon

Bluegill fishing at T Lake

Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Summer pushes them deeper, 4 to 15 ft, and winter fish settle into 10 to 25 ft. The spot to know is Deep basin, a deep basin in about 38 ft of water that rates good for bluegill in winter. Warm-month bites cluster around early morning and the evening. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 6 ft	midday & dusk	open water	1/32 oz jig + micro plastic, Tiny popper (evenings)
Summer	4 to 15 ft	dawn & dusk	open water	Small sponge spider (fly), Micro tube jig
Fall	6 to 18 ft	midday	open water	Micro jig + waxworm, Small spoon tipped
Winter	10 to 25 ft	midday	Deep basin (38 ft)	Tungsten ice jig + plastic, Tiny spoon

Pumpkinseed fishing at T Lake

Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 6 to 18 ft. Prime time lands in the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 8 ft	midday & dusk	open water	Micro jig under a float, Tiny beetle-spin
Summer	2 to 10 ft	dusk & dawn	open water	Micro tube, Sponge spider (fly)
Fall	4 to 14 ft	dusk & dawn	open water	Micro jig + waxworm, Small spoon tipped
Winter	6 to 18 ft	dawn	open water	Tungsten ice jig + plastic, Tiny spoon

Where is the best fishing spot on T Lake?

Main-lake point is the top-rated area: a point in about 11 ft of water that rates prime for largemouth bass in fall. Scroll up to the map for the complete spot list by species and season.

When is the best time to fish T Lake?

For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
