3,769-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 16 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 3,881 acres wrapped in 26.3 miles of bank, with 4 islands in the mix. A development index of 3 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 93% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 3.7 mi long by 2.7 mi wide at the broadest reach. Polk County claims this one. If the bite dies, Lake Hatchineha is 6 mi to the north.
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. If you only fish one area, make it Grass flat: a weed flat around 2 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Grass flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 16 ft | dawn & dusk | Contour break (4 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Grass flat (2 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 16 ft | midday | Contour break (4 ft) | Blade bait, Jigging spoon |
Come spring, look for crappie tight to the bank in 2 to 8 ft. Expect a summer slide to 5 to 16 ft, then a winter hold in 5 to 16 ft. Start at Deepest hole. It's a deep basin holding about 16 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Grass flat (2 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 16 ft | dawn & dusk | Deepest hole (16 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 16 ft | dawn | Deepest hole (16 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 16 ft | midday | Deepest hole (16 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 5 to 16 ft one. Start at Grass flat. It's a weed flat holding about 2 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Grass flat (2 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Grass flat (2 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 5 to 16 ft | midday | Contour break (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 16 ft | midday | Deepest hole (16 ft) | Tiny spoon |
When the water first warms, channel catfish slide up into 3 to 12 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. If you only fish one area, make it Deepest hole: a deep basin around 16 ft that scores prime in winter. In summer the feeding windows fall in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Grass flat (2 ft) | |
| Summer | 5 to 16 ft | night & dusk | Deepest hole (16 ft) | |
| Fall | 5 to 16 ft | dusk | Deepest hole (16 ft) | |
| Winter | 5 to 16 ft | midday | Deepest hole (16 ft) |
