185-acre lake near St. Louis County. The lake tops out around 135 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What follows comes from the same scoring engine that paints the spots above.
Gun maps at 185 acres behind 4.9 miles of shoreline. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 28% of the surface on the model — that's where the groceries are. Figure 1.2 mi of water from one end to the other, 0.8 mi at the beam. St. Louis County claims this one. Its nearest charted neighbour, Trygg, is 1 mi to the north.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 115 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (34 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (115 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (34 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (61 ft) | White tube jig, Airplane jig |
The spring pattern is a shallow one: cisco (lake herring) in 10 to 40 ft. Midsummer fish sit out in 40 to 80 ft before dropping to 20 to 60 ft for winter. The spot to know is Break off the point, a drop-off in about 61 ft of water that rates prime for cisco (lake herring) in winter. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | open water | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Break off the point (61 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (61 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 20 to 45 ft. Start at Main-lake point. It's a point holding about 34 ft of water and rates good come summer. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (34 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | open water | Blade bait, Hair jig |
Come spring, look for burbot tight to the bank in 25 to 70 ft. They move out to 50 to 120 ft in summer and finish the year down in 15 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 115 ft that scores prime in summer. Best bite is after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (61 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Deep basin (115 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (61 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (61 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
