38-acre lake near Dugger. A 38-acre strip-pit lake in Greene-Sullivan State Forest's Dugger Unit, a narrow reclaimed mine cut reaching 72 feet deep; shoreline from the USGS National Hydrography Dataset. The lake tops out around 72 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Long Lake (Greene-Sullivan) runs 47 acres with 1.6 miles of edge. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 42% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.7 mi, about 0.2 mi across. The water lies in Sullivan County. For a second option, Turtle Lake (Greene-Sullivan) lies 0 mi southwest.
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 15 to 35 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| 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 (18 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (32 ft) | Blade bait, Jigging spoon |
Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Summer pushes them deeper, 4 to 15 ft, and winter fish settle into 10 to 25 ft. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for bluegill in spring. Warm-month bites cluster around early morning and the evening. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.
| 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 |

| 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 | Break off the point (32 ft) | |
