58-acre lake in Sawyer County, Wisconsin. The lake tops out around 17 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
Hadley Lake maps at 58 acres behind 1.9 miles of shoreline. A middling shoreline index (1.8) gives it some bays to work without being a maze. 94% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 0.7 mi long by 0.3 mi wide at the broadest reach. Sawyer County claims this one. Its nearest charted neighbour, Red Ike Lake, is 1 mi to the southeast.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 5 to 17 ft, and winter fish settle into 5 to 17 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 17 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 17 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 17 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring largemouth bass on Hadley Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 5 to 17 ft, and by winter most fish are in 5 to 17 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 17 ft | dawn & dusk | Main-lake point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 17 ft | midday | Deep basin (14 ft) | Blade bait, Jigging spoon |
Early season crappie use the shallows, holding in 2 to 8 ft. Expect a summer slide to 5 to 17 ft, then a winter hold in 5 to 17 ft. Put Deep basin first on the milk run — a deep basin near 14 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 17 ft | dawn & dusk | Deep basin (14 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 17 ft | dawn | Deep basin (14 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 17 ft | midday | Deep basin (14 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season bluegill use the shallows, holding in 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 5 to 17 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |

| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 17 ft | dawn | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |

Anglers target yellow perch, largemouth bass, crappie, bluegill, pumpkinseed on Hadley Lake. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Every other rated spot, per species and season, is on the map above.
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.
