124-acre lake near Big Stone County. The lake tops out around 4 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Here's the year, species by species, as the scoring engine sees it.
Lannon maps at 124 acres behind 2.5 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.7 mi, about 0.5 mi across. It sits in Big Stone County. East Toqua sits 1 mi northwest — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 1 to 4 ft. The depth story barely changes: 1 to 4 ft through summer, 1 to 4 ft in winter. The spot to know is Break off the point, a drop-off in about 2 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
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 | 1 to 4 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 1 to 4 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (2 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 1 to 4 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (2 ft) | Jigging rap, Jig + big minnow |
| Winter | 1 to 4 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (3 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 1 to 4 ft. Summer keeps them at 1 to 4 ft, and they winter in 1 to 4 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. 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 | 1 to 4 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

Early season northern pike use the shallows, holding in 1 to 4 ft. Even in summer they hold at 1 to 4 ft; winter keeps them in 1 to 4 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.

Early season crappie use the shallows, holding in 1 to 4 ft. Even in summer they hold at 1 to 4 ft; winter keeps them in 1 to 4 ft. The chart's best answer is Deep basin — deep basin, 3 ft, prime for winter. Best bite is early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.

When the water first warms, common carp slide up into 1 to 4 ft. There's no big seasonal slide here — summer means 1 to 4 ft, winter 1 to 4 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening.

Spring puts black bullhead in skinny water — 1 to 4 ft is the zone. Summer fish stay in 1 to 4 ft, and winter fish hold in 1 to 4 ft. Deep basin is the standout, a deep basin at roughly 3 ft, rated prime for winter black bullhead. Plan around after dark and the evening in the warm months.
