Rating depth structure for smallmouth bass.

85-acre lake near Iron County. The lake tops out around 23 ft. The depth chart comes from published agency 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.
| 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 | dawn & dusk | Break off the point (15 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 7 to 23 ft | midday & dawn | Break off the point (15 ft) | Jerkbait, Blade bait |
| Winter | 7 to 23 ft | midday | Break off the point (15 ft) | Blade bait, Hair jig |
