46-acre lake near Lake County. The lake tops out around 7 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 46 acres wrapped in 2.2 miles of bank. An index of 2.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Call it 0.9 mi long by 0.2 mi wide at the broadest reach. It sits in Lake County. Its nearest charted neighbour, Legler, is 4 mi to the southeast.
Early season brook trout use the shallows, holding in 1 to 7 ft. Even in summer they hold at 2 to 7 ft; winter keeps them in 1 to 7 ft. Put Deep basin first on the milk run — a deep basin near 6 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 7 ft chart-limited; documented 2 to 15 ft | dawn & dusk | Main-lake point (7 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 7 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (6 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 7 ft chart-limited; documented 2 to 15 ft | midday & dawn | Main-lake point (7 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 7 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring rainbow trout on Sullivan hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 1 to 7 ft once it turns cold. The chart's best answer is Break off the point — drop-off, 3 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.

| Winter | 1 to 7 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (3 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: yellow perch in 2 to 7 ft. The depth story barely changes: 2 to 7 ft through summer, 2 to 7 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

| Spring | 2 to 7 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

When the water first warms, northern pike slide up into 2 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 2 to 7 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 7 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 7 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 7 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 2 to 7 ft, then a winter hold in 2 to 7 ft. Start at Shallow bay flat. It's a weed flat holding about 3 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.

| Winter | 2 to 7 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: pumpkinseed sit in 1 to 7 ft that time of year. They don't go far with the seasons — 1 to 7 ft covers summer, 2 to 7 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for pumpkinseed in spring. Warm-month bites cluster around the evening and early morning. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
