52-acre lake in Kenosha County, Wisconsin. The lake tops out around 33 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Rock Lake runs 52 acres with 1.3 miles of edge. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 59% of the surface on the model — that's where the groceries are. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. You'll find it in Kenosha County. For a second option, Cross Lake lies 2 mi east.
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 7 to 33 ft. Top water on the chart: Shoreline break, a drop-off in the 15 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shoreline break (15 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shoreline break (15 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 33 ft | dawn & dusk | Shoreline break (15 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 7 to 33 ft | dawn | Shoreline break (15 ft) | Jigging spoon, Tube jig (white) |
Spring yellow perch on Rock Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 10 to 33 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft | midday | Deep basin (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 10 to 33 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shoreline break (15 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (4 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 10 to 33 ft | midday | Shoreline break (15 ft) | Blade bait, Jigging spoon |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 10 to 25 ft; cold water stacks them in 10 to 33 ft. Deep basin is the standout, a deep basin at roughly 28 ft, rated prime for winter crappie. Plan around early morning and the evening in the warm months. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shoreline break (15 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shoreline break (15 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 10 to 33 ft | midday | Deep basin (28 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
