Rating depth structure for bluegill.
Shared by DepthScout anglers. Exact spots stay private, always.
8-acre lake near Dugger. An 8-acre farm-pond lake in Greene-Sullivan State Forest's Dugger Unit stocked for bluegill, redear and catfish; shoreline from the USGS National Hydrography Dataset. The lake tops out around 25 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.
Drawn out, this is 10 acres of water rimmed by 0.8 miles of bank. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 40% of this chart, as modeled. The water lies in Sullivan County. Closest neighbour on DepthScout: Duck Lake (Greene-Sullivan), 0 mi south of here.
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 Deep basin, a deep basin in about 21 ft of water that rates prime for bluegill in winter. 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 | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (11 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (21 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring puts channel catfish in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 8 to 25 ft, wintering in 8 to 25 ft. Winter channel catfish concentrate at Deep basin, a prime-rated deep basin around 21 ft. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
