36-acre reservoir in Vernon County, Wisconsin. The lake tops out around 22 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Sidie Hollow Lake runs 36 acres with 1.9 miles of edge. With a shoreline index of 2.2, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 90% of the water is 15 ft or less as modeled, the band where the food chain lives. Call it 0.6 mi long by 0.4 mi wide at the broadest reach. You'll find it in Vernon County. The nearest mapped water is Runge Hollow Lake, 6 mi to the northwest.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Summer pushes them deeper, 6 to 22 ft, and winter fish settle into 4 to 22 ft. The spot to know is Main-lake point, a point in about 8 ft of water that rates prime for rainbow trout in spring. Warm-month bites cluster around early morning and the evening. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 6 to 22 ft | dawn & dusk | Main-lake point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 22 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 22 ft | dawn | Deep basin (19 ft) | Jigging spoon, Tube jig (white) |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is a 7 to 22 ft game here, winter a 7 to 22 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| 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 | 7 to 22 ft | dawn | Deep basin (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 22 ft | midday | Deep basin (19 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 22 ft | midday & dawn | Deep basin (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 7 to 22 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 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 | 7 to 22 ft | midday | Deep basin (19 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 7 to 22 ft before dropping to 7 to 22 ft for winter. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 19 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
| 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 | 7 to 22 ft | dawn & dusk | Deep basin (19 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Deep basin (19 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 7 to 22 ft | midday | Deep basin (19 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Warm water sends them out to 4 to 15 ft; cold water stacks them in 7 to 22 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| 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 | 7 to 22 ft | midday | Deep basin (19 ft) | Tungsten ice jig + plastic, Tiny spoon |
