100-acre lake near St. Louis County. The lake tops out around 14 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. What the data behind the map says about each species, season by season:
Drawn out, this is 100 acres of water rimmed by 2.7 miles of bank. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. The basin spans about 0.8 mi end to end and 0.4 mi across at its widest. You'll find it in St. Louis County. For a second option, Little Crab lies 1 mi east.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 4 to 14 ft game here, winter a 4 to 14 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
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 | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 14 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 4 to 14 ft before dropping to 4 to 14 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 14 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 14 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 14 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 4 to 14 ft before dropping to 4 to 14 ft for winter. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 8 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.

Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 4 to 14 ft; cold water stacks them in 4 to 14 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |

| Winter | 4 to 14 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (6 ft) | Blade bait, Jigging spoon |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. They move out to 4 to 14 ft in summer and finish the year down in 4 to 14 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in summer. Best bite is the evening. A ned rig (small) or a marabou jig is the honest summer answer here.

Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 14 ft; cold water stacks them in 4 to 14 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
