115-acre lake. Hydroacoustic-surveyed Florida lake (FWC), recovered from a water-connected survey blob by joining contours to its USGS NHD named-waterbody polygon. Standard Florida warmwater roster; species not individually verified. The lake tops out around 15 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Lake Idylwild runs 121 acres with 1.6 miles of edge. A shoreline index of 1 says round and simple: fish relate to depth changes here, not shoreline features. Call it 0.5 mi long by 0.5 mi wide at the broadest reach. You'll find it in Polk County. The nearest mapped water is Lake Jessie, 1 mi to the northwest.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 5 to 15 ft; cold water stacks them in 5 to 15 ft. Grass flat is the standout, a weed flat at roughly 5 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 | Grass flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 15 ft | dawn & dusk | Contour break (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Grass flat (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 15 ft | midday | Contour break (10 ft) | Blade bait, Jigging spoon |
In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 5 to 15 ft before dropping to 5 to 15 ft for winter. Winter crappie concentrate at Deepest hole, a prime-rated deep basin around 15 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 | Grass flat (5 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 15 ft | dawn & dusk | Grass flat (5 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 15 ft | dawn | Contour break (10 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 15 ft | midday | Deepest hole (15 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 5 to 15 ft. Top water on the chart: Grass flat, a weed flat in the 5 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 | Grass flat (5 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Grass flat (5 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 5 to 15 ft | midday | Grass flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 15 ft | midday | Deepest hole (15 ft) | Tiny spoon |
Spring puts channel catfish in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 5 to 15 ft; cold water stacks them in 5 to 15 ft. Deepest hole is the standout, a deep basin at roughly 15 ft, rated prime for winter channel catfish. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Grass flat (5 ft) | |
| Summer | 5 to 15 ft | night & dusk | Deepest hole (15 ft) | |
| Fall | 5 to 15 ft | dusk | Deepest hole (15 ft) | |
| Winter | 5 to 15 ft | midday | Deepest hole (15 ft) |

Grass flat is the top-rated area: a weed flat in about 5 ft of water that rates prime for largemouth bass in spring. The interactive chart above rates every spot for each species and season.
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.
