107-acre lake. Hydroacoustic-surveyed Florida lake (FWC). Standard Florida warmwater roster; species not individually verified. The lake tops out around 26 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.
Lake Martha maps at 113 acres behind 1.6 miles of shoreline. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. About 57% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.5 mi of water from one end to the other, 0.4 mi at the beam. It sits in Polk County. Lake Buckeye sits 1 mi northeast — the closest neighbouring chart.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 8 to 26 ft. If you only fish one area, make it Grass flat: a weed flat around 5 ft that scores prime in spring. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Grass flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Contour break (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Grass flat (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 8 to 26 ft | midday | Contour break (9 ft) | Blade bait, Jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Start at Grass flat. It's a weed flat holding about 5 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| 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 | 6 to 18 ft | midday | Contour break (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deepest hole (26 ft) | Tiny spoon |
When the water first warms, crappie slide up into 2 to 8 ft. Summer is a 10 to 25 ft game here, winter an 8 to 26 ft one. Start at Deepest hole. It's a deep basin holding about 26 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| 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 | 10 to 25 ft | dawn & dusk | Contour break (9 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Contour break (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 8 to 26 ft | midday | Deepest hole (26 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Come spring, look for channel catfish tight to the bank in 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 8 to 26 ft. If you only fish one area, make it Deepest hole: a deep basin around 26 ft that scores prime in winter. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Grass flat (5 ft) | |
| Summer | 8 to 25 ft | night & dusk | Deepest hole (26 ft) | |
| Fall | 8 to 26 ft | dusk | Deepest hole (26 ft) | |
| Winter | 8 to 26 ft | midday | Deepest hole (26 ft) |
