108-acre lake near St. Louis County. The lake tops out around 10 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Minnesota DNR survey of 1958, a decades-old survey (the DNR's original lake-survey map). The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 108 acres wrapped in 2.7 miles of bank. A middling shoreline index (1.9) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 0.7 mi long by 0.4 mi wide at the broadest reach. It sits in St. Louis County. If the bite dies, Clearwater is 2 mi to the southwest.
In spring, yellow perch run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 10 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.
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 10 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 10 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 10 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 3 to 10 ft game here, winter a 3 to 10 ft one. The chart's best answer is Break off the point — drop-off, 3 ft, prime for fall. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.

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

Early season smallmouth bass use the shallows, holding in 3 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 3 to 10 ft. The chart's best answer is Break off the point — drop-off, 3 ft, prime for winter. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.

Early season crappie use the shallows, holding in 2 to 8 ft. Summer is a 3 to 10 ft game here, winter a 3 to 10 ft one. The chart's best answer is Deep basin — deep basin, 10 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.

| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | 1/16 oz jig + tube, Curly-tail grub |

Early season bluegill use the shallows, holding in 1 to 6 ft. Expect a summer slide to 3 to 10 ft, then a winter hold in 3 to 10 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.

Spring largemouth bass on Flowage hold shallow, usually 2 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 3 to 10 ft once it turns cold. Put Break off the point first on the milk run — a drop-off near 3 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
