80-acre lake near Hemelum. The lake tops out around 12 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
The outline encloses 80 acres, worked by 1.9 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. End to end it runs roughly 0.6 mi, about 0.5 mi across. Its nearest charted neighbour, Morra, is 1 mi to the east.

Come spring, look for european perch tight to the bank in 3 to 12 ft. Through summer count on 3 to 12 ft; the winter hold is 4 to 12 ft. Start at Measured deep-water basin. It's a deep basin holding about 12 ft of water and rates prime come fall. Prime time lands in early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Measured shallow feeding flat (4 ft) | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 3 to 12 ft | dawn | Measured deep-water basin (12 ft) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 4 to 12 ft | midday | Measured deep-water basin (12 ft) | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 4 to 12 ft | midday & dawn | Measured deep-water basin (12 ft) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 4 to 12 ft, then a winter hold in 4 to 12 ft. Put Measured shallow feeding flat first on the milk run — a feeding flat near 4 ft that grades prime for spring. In summer the feeding windows fall in 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 |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Measured shallow feeding flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 4 to 12 ft | dawn & dusk | Measured shallow feeding flat (4 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 12 ft | midday & dawn | Measured shallow feeding flat (4 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 12 ft | midday | Measured shallow feeding flat (4 ft) | Tip-ups, Large jigging spoon |
When the water first warms, common carp slide up into 2 to 10 ft. Summer is a 2 to 12 ft game here, winter a 4 to 12 ft one. Start at Measured deep-water basin. It's a deep basin holding about 12 ft of water and rates prime come winter. The feeding windows run early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Measured shallow feeding flat (4 ft) | |
| Summer | 2 to 12 ft | dawn & dusk | Measured shallow feeding flat (4 ft) | |
| Fall | 3 to 12 ft | midday | Measured shallow feeding flat (4 ft) | |
| Winter | 4 to 12 ft | midday | Measured deep-water basin (12 ft) |
Structure-wise the chart holds 2 features, led in depth by Measured deep-water basin at roughly 12 ft.
