3,267-acre lake. Hydroacoustic-surveyed Florida lake (FWC). Standard Florida warmwater roster; species not individually verified. The lake tops out around 9 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
On the chart, Lake Poinsett draws 3,373 acres inside 37.7 miles of shoreline, broken up by 7 islands. With a shoreline index of 4.6, this water is all arms and coves — edge habitat well beyond its acreage. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 5.5 mi of water from one end to the other, 2.3 mi at the beam. The water lies in Brevard County. The nearest mapped water is Lake Winder, 6 mi to the south.
Start shallow in spring: largemouth bass sit in 2 to 9 ft that time of year. They don't go far with the seasons — 3 to 9 ft covers summer, 3 to 9 ft covers winter. The spot to know is Grass flat, a weed flat in about 2 ft of water that rates prime for largemouth bass in spring. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dawn & dusk | Grass flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 9 ft | dawn & dusk | Contour break (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 9 ft | midday & dawn | Grass flat (2 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 9 ft | midday | Contour break (3 ft) | Blade bait, Jigging spoon |
Spring puts bluegill in skinny water — 1 to 6 ft is the zone. As the season builds they drop to 2 to 9 ft, wintering in 3 to 9 ft. Spring bluegill concentrate at Grass flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around early morning and the evening. A small sponge spider (fly) or a micro tube jig covers the summer program.
| 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 | 2 to 9 ft | dawn & dusk | Grass flat (2 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 3 to 9 ft | midday | Contour break (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 9 ft | midday | Deepest hole (9 ft) | Tiny spoon |
The spring pattern is a shallow one: crappie in 2 to 8 ft. As the season builds they drop to 3 to 9 ft, wintering in 3 to 9 ft. Top water on the chart: Deepest hole, a deep basin in the 9 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
| 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 | 3 to 9 ft | dawn & dusk | Contour break (3 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 3 to 9 ft | dawn | Contour break (3 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 3 to 9 ft | midday | Deepest hole (9 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: channel catfish sit in 2 to 9 ft that time of year. They don't go far with the seasons — 3 to 9 ft covers summer, 3 to 9 ft covers winter. The spot to know is Deepest hole, a deep basin in about 9 ft of water that rates prime for channel catfish in winter. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dusk | Grass flat (2 ft) | |
| Summer | 3 to 9 ft | night & dusk | Deepest hole (9 ft) | |
| Fall | 3 to 9 ft | dusk | Deepest hole (9 ft) | |
| Winter | 3 to 9 ft | midday | Deepest hole (9 ft) |
Structure-wise the chart holds 11 features, led in depth by Deepest hole at roughly 9 ft.
