14-acre lake in Iron County, Wisconsin. The lake tops out around 8 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. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 14 acres of water rimmed by 0.7 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.3 mi. The water lies in Iron County. The nearest mapped water is Grant Lake, 1 mi to the southwest.
Early season yellow perch use the shallows, holding in 2 to 8 ft. Even in summer they hold at 2 to 8 ft; winter keeps them in 2 to 8 ft. Put Deep basin first on the milk run — a deep basin near 7 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 | 2 to 8 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 8 ft | dawn | Deep basin (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 8 ft | midday | Deep basin (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 8 ft | midday & dawn | Deep basin (7 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts largemouth bass in skinny water — 2 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 2 to 8 ft. Fall largemouth bass concentrate at Main-lake point, a prime-rated point around 8 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 8 ft | dawn & dusk | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 8 ft | dawn & dusk | Break off the point (4 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 8 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 8 ft | midday | Break off the point (4 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Summer keeps them at 2 to 8 ft, and they winter in 2 to 8 ft. Deep basin is the standout, a deep basin at roughly 7 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 | 2 to 8 ft | dawn & dusk | Break off the point (4 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 2 to 8 ft | dawn | Break off the point (4 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 2 to 8 ft | midday | Deep basin (7 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Summer pushes them deeper, 2 to 8 ft, and winter fish settle into 2 to 8 ft. The spot to know is Deep basin, a deep basin in about 7 ft of water that rates prime 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 | 2 to 8 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 2 to 8 ft | midday | Break off the point (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 8 ft | midday | Deep basin (7 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. Through summer count on 2 to 8 ft; the winter hold is 2 to 8 ft. Start at Deep basin. It's a deep basin holding about 7 ft of water and rates prime come winter. 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 8 ft | dusk & dawn | open water | Micro tube, Sponge spider (fly) |
| Fall | 2 to 8 ft | dusk & dawn | Break off the point (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 2 to 8 ft | dawn | Deep basin (7 ft) | Tungsten ice jig + plastic, Tiny spoon |

North Grant Lake is about 8 ft (2 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, largemouth bass, crappie, bluegill, pumpkinseed on North Grant 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.
Deep basin is the top-rated area: a deep basin in about 7 ft of water that rates prime for yellow perch in fall. The interactive chart above rates every spot for each species and season.
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.
