54-acre lake in Iron County, Wisconsin. The lake tops out around 5 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 56 acres, worked by 1.4 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. It sits in Iron County. Sister Lakes sits 1 mi northeast — the closest neighbouring chart.
Early season northern pike use the shallows, holding in 1 to 5 ft. Even in summer they hold at 2 to 5 ft; winter keeps them in 2 to 5 ft. 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 bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 5 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 5 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 5 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Spring largemouth bass on Island Lake hold shallow, usually 1 to 5 ft. Depth-wise the year is flat: 2 to 5 ft in summer, 2 to 5 ft once it turns cold. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run 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 | 1 to 5 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 2 to 5 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 1 to 5 ft | midday & dawn | Main-lake point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 2 to 5 ft | midday | Break off the point (2 ft) | Blade bait, Jigging spoon |

Island Lake is about 5 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 northern pike, largemouth bass on Island 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 northern pike in spring. The map above holds the full rated-spot list for every species and season.
For northern pike, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
