Rating depth structure for smallmouth bass.
Recent public catches load as you reach this section.
85-acre lake near Iron County. The lake tops out around 23 ft. The depth chart comes from Michigan Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 85 acres wrapped in 1.6 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. About 80% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.6 mi, about 0.4 mi across. It sits in Iron County. If the bite dies, Gilbert Lake is 1 mi to the east.
Spring smallmouth bass on Gibson Lake hold shallow, usually 3 to 12 ft. They move out to 7 to 23 ft in summer and finish the year down in 7 to 23 ft. Put Break off the point first on the milk run — a drop-off near 15 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 7 to 23 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (15 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 7 to 23 ft chart-limited; documented 8 to 25 ft | midday & dawn | Break off the point (15 ft) | Jerkbait, Blade bait |
| Winter | 7 to 23 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (15 ft) | Blade bait, Hair jig |
Spring bluegill on Gibson Lake hold shallow, usually 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 7 to 23 ft. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (15 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 7 to 23 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (23 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 7 to 23 ft one. The chart's best answer is Break off the point — drop-off, 15 ft, prime for winter. Best bite is early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (1 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 7 to 23 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
Spring northern pike on Gibson Lake hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Break off the point first on the milk run — a drop-off near 15 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (15 ft) | Tip-ups, Large jigging spoon |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 7 to 23 ft; cold water stacks them in 7 to 23 ft. Deep basin is the standout, a deep basin at roughly 23 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
