25-acre lake near Dugger. A deep Greene-Sullivan State Forest strip-pit stocked with rainbow trout. The lake tops out around 67 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 season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 32 acres wrapped in 2.2 miles of bank. That shoreline is heavily fingered (development index 2.8) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 67% of this chart, as modeled. Tip to tip the water measures near 0.8 mi with a 0.2-mi widest point. Greene County claims this one. If the bite dies, Reservoir 26 is 1 mi to the southwest.
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter an 8 to 40 ft one. The chart's best answer is Main-lake point — point, 17 ft, prime for spring. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (17 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (17 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (17 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | open water | Jigging spoon, Tube jig (white) |
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 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 | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (17 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (17 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | open water | Blade bait, 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 10 to 25 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 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 | Shallow bay flat (6 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (57 ft) | Tungsten ice jig + plastic, Tiny spoon |
When the water first warms, channel catfish slide up into 3 to 12 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 20 to 40 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores good in spring. 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 | Shallow bay flat (6 ft) | |
| Summer | 8 to 25 ft | night & dusk | open water | |
| Fall | 10 to 30 ft | dusk | Deep basin (57 ft) | |
| Winter | 20 to 40 ft | midday | Deep basin (57 ft) |
