117-acre lake near St. Louis County. The lake tops out around 55 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:
The drawn water covers 117 acres wrapped in 3.7 miles of bank. An index of 2.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 58% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 0.7 mi, about 0.6 mi across. It sits in St. Louis County. Its nearest charted neighbour, North Hegman, is 1 mi to the north.
Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 17 to 55 ft, wintering in 17 to 55 ft. Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 47 ft. Warm-month bites cluster around early morning. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.
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 | 10 to 40 ft | dawn & dusk | Deep basin (47 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 17 to 55 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (47 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (25 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 17 to 55 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (47 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 25 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (14 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (25 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (25 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (25 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring 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.
| 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 | Break off the point (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (25 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (25 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on South Hegman 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 Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. 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 (6 ft) | #5 inline spinner, Spoon (red/white) |

Spring smallmouth bass on South Hegman hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 20 to 45 ft. Put Main-lake point first on the milk run — a point near 14 ft that grades prime for fall. 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 (14 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (25 ft) | Drop shot (goby/minnow), Ned rig |
