25-acre lake near Iron County. The lake tops out around 18 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 27 acres wrapped in 0.9 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 83% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. Iron County claims this one. Tepee Lake sits 1 mi east — the closest neighbouring chart.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 5 to 18 ft, and winter fish settle into 5 to 18 ft. Deep basin is the standout, a deep basin at roughly 18 ft, rated prime for fall 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 | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 18 ft | dawn | Deep basin (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 18 ft | midday | Deep basin (18 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 18 ft | midday & dawn | Deep basin (18 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 5 to 18 ft, then a winter hold in 5 to 18 ft. Put Secondary point first on the milk run — a point near 6 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
| Summer | 5 to 18 ft | dawn & dusk | Break off the point (13 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 18 ft | midday & dawn | Secondary point (6 ft) | Jerkbait, Blade bait |
| Winter | 5 to 18 ft | midday | Break off the point (13 ft) | Blade bait, Hair jig |
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 18 ft one. The chart's best answer is Deep basin — deep basin, 18 ft, prime for winter. 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 | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (13 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 18 ft | midday | Deep basin (18 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season brown bullhead use the shallows, holding in 2 to 8 ft. Summer is a 3 to 12 ft game here, winter a 5 to 18 ft one. The chart's best answer is Deep basin — deep basin, 18 ft, prime for winter. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | open water | |
| Summer | 3 to 12 ft | night & dusk | open water | |
| Fall | 5 to 15 ft | dusk | Deep basin (18 ft) | |
| Winter | 5 to 18 ft | midday | Deep basin (18 ft) |
