33-acre lake near Osceola County. The lake tops out around 32 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
There are 1.2 miles of drawn shoreline to work. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 71% of the surface — that's where the groceries are. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Osceola County. For a second option, Penasa Lake lies 1 mi south.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 29 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Tungsten jig + plastic |
The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 6 to 32 ft for winter. The spot to know is Break off the point, a drop-off in about 16 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 32 ft | dawn & dusk | Secondary point (13 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 32 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
Early season brown trout use the shallows, holding in 3 to 25 ft. Summer is a 10 to 32 ft game here, winter a 5 to 32 ft one. The chart's best answer is Break off the point — drop-off, 16 ft, prime for summer. Best bite is after dark and early morning. Tie on a spoon at the thermocline or a deep stickbait (night) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 10 to 32 ft | night & dawn | Break off the point (16 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (8 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 5 to 32 ft | dawn | Break off the point (16 ft) | Jigging spoon, Small stickbait (slow) |
Spring yellow perch on McCoy Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 10 to 32 ft. The chart's best answer is Deep basin — deep basin, 29 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Fall northern pike concentrate at Break off the point, a prime-rated drop-off around 16 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (16 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (16 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Main-lake point (8 ft) | Tip-ups, Large jigging spoon |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 10 to 32 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
