218-acre lake near Harlan. The lake tops out around 22 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Prairie Rose Lake runs 197 acres with 5.9 miles of edge. With a shoreline index of 3, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 85% of the water is 15 ft or less, the band where the food chain lives. Call it 1.3 mi long by 0.9 mi wide at the broadest reach. You'll find it in Shelby County. The nearest mapped water is Atlantic Quarry Pond 2, 17 mi to the southeast.
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 7 to 22 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 2 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.
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 | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 7 to 22 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (5 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: bluegill in 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 7 to 22 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 2 ft of water that rates prime for bluegill in spring. Plan around early morning and the evening in the warm months. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Back-bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 7 to 22 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (21 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 7 to 22 ft; cold water stacks them in 7 to 22 ft. Deep basin is the standout, a deep basin at roughly 21 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.

| Winter | 7 to 22 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (21 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
In spring, channel catfish run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 7 to 22 ft before dropping to 7 to 22 ft for winter. Winter channel catfish concentrate at Deep basin, a prime-rated deep basin around 21 ft. Fish it in after dark and the evening and you'll meet the bite.

Prairie Rose Lake is about 22 ft (7 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target largemouth bass, bluegill, crappie, channel catfish on Prairie Rose Lake.
Shallow bay flat is the top-rated area: a weed flat in about 2 ft of water that rates prime for largemouth bass in spring. Every other rated spot, per species and season, is on the map above.
For largemouth bass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
