533-acre Sculpin Ledge Channel fishing map with NOAA BlueTopo survey contours (88.09% measured, 99.49% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 28 ft. The depth chart is built from real agency bathymetry referenced to NAVD88; directly measured coverage remains distinguished from source interpolation. The channels, holes and drop-offs come from the source data, not a distance-from-shore model. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Sculpin Ledge Channel runs 532 acres with 4.2 miles of edge. Nearly circular (index 1.3), so the story is the bottom, not the bank. 35% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 1.5 mi of water from one end to the other, 1.2 mi at the beam. The nearest mapped water is President Roads, 1 mi to the north.
Spring striped bass on Sculpin Ledge Channel hold shallow, usually 5 to 20 ft. They move out to 8 to 28 ft in summer and finish the year down in 8 to 28 ft. Put Surveyed channel edge first on the milk run — a drop-off near 15 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a flutter spoon (deep) or an umbrella rig (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (15 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 8 to 28 ft | dawn & dusk | Surveyed channel edge (15 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 8 to 28 ft | dawn & dusk | Surveyed channel edge (15 ft) | Topwater walker, Jerkbait |
| Winter | 8 to 28 ft | midday | Surveyed channel edge (15 ft) | Alabama rig (slow), Flutter spoon |
Spring puts bluefish in skinny water — 3 to 20 ft is the zone. As the season builds they drop to 5 to 28 ft, wintering in 8 to 28 ft. Summer bluefish concentrate at Surveyed channel edge, a prime-rated drop-off around 15 ft. Warm-month bites cluster around early morning and the evening. A popper (early/late) or a metal jigs in the rips covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Shallow feeding flat (17 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 28 ft | dawn & dusk | Surveyed channel edge (15 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Shallow feeding flat (17 ft) | Pencil popper, Big metal |
| Winter | 8 to 28 ft | midday | Surveyed channel edge (15 ft) | Metal jig worked slow (southern waters) |
Spring black sea bass on Sculpin Ledge Channel hold shallow, usually 7 to 28 ft. Depth-wise the year is flat: 7 to 28 ft in summer, 8 to 28 ft once it turns cold. Put NOAA charted underwater rock first on the milk run — a rock pile near 11 ft that grades prime for spring. The feeding windows run midday and early morning. The summer box starts with a bucktail + grub or a diamond jig + squid teaser.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 28 ft | midday & dawn | NOAA charted underwater rock (11 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 7 to 28 ft | midday & dawn | NOAA charted underwater rock (11 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 7 to 28 ft | midday | NOAA charted underwater rock (11 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 8 to 28 ft | midday | NOAA charted underwater rock (11 ft) | Heavy hi-lo rig on deep wrecks |
The spring pattern is a shallow one: tautog (blackfish) in 5 to 25 ft. Midsummer fish sit out in 8 to 28 ft before dropping to 8 to 28 ft for winter. The spot to know is NOAA charted wreck, a wreck in about 5 ft of water that rates prime for tautog (blackfish) in spring. Plan around early morning in the warm months. Summer baits: a 1/2-1 oz tog jig + crab gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | NOAA charted wreck (5 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 8 to 28 ft | dawn | NOAA charted underwater rock (11 ft) | 1/2-1 oz tog jig + crab |
| Fall | 6 to 28 ft | midday | NOAA charted underwater rock (6 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 8 to 28 ft | midday | NOAA charted underwater rock (11 ft) | Heavy jig + crab on deep structure |
Early season atlantic mackerel use the shallows, holding in 3 to 28 ft. Even in summer they hold at 5 to 28 ft; winter keeps them in 7 to 28 ft. Put Surveyed channel edge first on the milk run — a drop-off near 15 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a feather rig or a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 28 ft | dawn & dusk | Surveyed channel edge (15 ft) | Mackerel feather rig, Small silver jig |
| Summer | 5 to 28 ft | dawn & dusk | Surveyed channel edge (15 ft) | Feather rig, Small vertical jig |
| Fall | 4 to 28 ft | dawn & dusk | Surveyed channel edge (15 ft) | Compact silver jig, Sparse feather rig |
| Winter | 7 to 28 ft | midday | Surveyed channel edge (15 ft) | Small deep jig |
Come spring, look for atlantic cod tight to the bank in 6 to 28 ft. Through summer count on 7 to 28 ft; the winter hold is 6 to 28 ft. Start at NOAA charted underwater rock. It's a rock pile holding about 6 ft of water and rates prime come spring. Prime time lands in early morning. A heavy metal jig or a large soft-plastic jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 28 ft | dawn | NOAA charted underwater rock (6 ft) | Diamond jig, Heavy bucktail |
| Summer | 7 to 28 ft | dawn | NOAA charted underwater rock (11 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 5 to 28 ft | dawn | NOAA charted underwater rock (6 ft) | Diamond jig, Bucktail with teaser |
| Winter | 6 to 28 ft | midday | NOAA charted underwater rock (6 ft) | Heavy vertical jig |
