14-acre lake in Monroe County, Wisconsin. The lake tops out around 19 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What the data behind the map says about each species, season by season:
Suukjak Sep Lake maps at 14 acres behind 1.5 miles of shoreline. The 2.8 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 83% of this chart, as modeled. The basin spans about 0.7 mi end to end. Monroe County claims this one. Its nearest charted neighbour, Angelo Pond, is 5 mi to the southwest.
Spring rainbow trout on Suukjak Sep Lake hold shallow, usually 5 to 19 ft. Depth-wise the year is flat: 5 to 19 ft in summer, 4 to 19 ft once it turns cold. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 19 ft | dawn | Deep basin (16 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 6 to 19 ft, wintering in 6 to 19 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| 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 | 6 to 19 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 19 ft | midday | Deep basin (16 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 19 ft | midday & dawn | Deep basin (16 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 6 to 19 ft, and by winter most fish are in 5 to 15 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. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| 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 | 6 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 6 to 19 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 6 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Blade bait, Jigging spoon |
When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 6 to 19 ft, and by winter most fish are in 6 to 19 ft. If you only fish one area, make it Deep basin: a deep basin around 16 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 6 to 19 ft | dawn & dusk | Deep basin (16 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 6 to 19 ft | dawn | Deep basin (16 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 6 to 19 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. Best bite is early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Tungsten ice jig + plastic, Tiny spoon |
