4,519-acre South Oyster Bay fishing map with NOAA BlueTopo survey contours (93.23% measured, 98.5% assessed), source-traceable coastal structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 34 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. Species by species, here's what the data says the year looks like.
On the chart, South Oyster Bay draws 4,515 acres inside 69 miles of shoreline — 53 islands included. An index of 7.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 4.6 mi long by 3.4 mi wide at the broadest reach. Closest neighbour on DepthScout: Sloop Channel, 5 mi southwest of here.
Spring striped bass on South Oyster Bay hold shallow, usually 5 to 20 ft. By summer they slide out to 10 to 34 ft, and by winter most fish are in 10 to 34 ft. The chart's best answer is Surveyed channel edge — drop-off, 12 ft, prime for summer. Prime time lands in 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 | Shoreline point (4 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 10 to 34 ft | dawn & dusk | Surveyed channel edge (12 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 34 ft | dawn & dusk | Surveyed channel edge (12 ft) | Topwater walker, Jerkbait |
| Winter | 10 to 34 ft | midday | Surveyed channel edge (12 ft) | Alabama rig (slow), Flutter spoon |
Spring puts bluefish in skinny water — 3 to 20 ft is the zone. Warm water sends them out to 5 to 30 ft; cold water stacks them in 10 to 34 ft. NOAA charted groin is the standout, a jetty / riprap at roughly 14 ft, rated prime for summer bluefish. Plan around early morning and the evening in the warm months. 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 | Surveyed channel edge (9 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | NOAA charted groin (14 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (9 ft) | Pencil popper, Big metal |
| Winter | 10 to 34 ft | midday | Surveyed channel edge (12 ft) | Metal jig worked slow (southern waters) |
Early season summer flounder (fluke) use the shallows, holding in 5 to 25 ft. Summer is an 8 to 34 ft game here, winter a 10 to 34 ft one. The chart's best answer is Surveyed channel edge — drop-off, 9 ft, prime for summer. Best bite is midday and early morning. Tie on a bucktail (1-3 oz by drift speed) or a gulp grub on jighead and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Surveyed channel edge (9 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 8 to 34 ft | midday & dawn | Surveyed channel edge (9 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 9 to 34 ft | midday | Surveyed channel edge (9 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 10 to 34 ft | midday | Surveyed channel edge (12 ft) | Slow bottom rig + strip |
Spring black sea bass on South Oyster Bay hold shallow, usually 9 to 34 ft. Depth-wise the year is flat: 9 to 34 ft in summer, 10 to 34 ft once it turns cold. The chart's best answer is NOAA charted groin — jetty / riprap, 14 ft, prime for spring. Prime time lands in 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 | 9 to 34 ft | midday & dawn | NOAA charted groin (14 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 9 to 34 ft | midday & dawn | NOAA charted groin (14 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 9 to 34 ft | midday | NOAA charted groin (14 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 10 to 34 ft | midday | NOAA charted groin (14 ft) | Heavy hi-lo rig on deep wrecks |
The spring pattern is a shallow one: tautog (blackfish) in 5 to 25 ft. As the season builds they drop to 10 to 34 ft, wintering in 10 to 34 ft. Top water on the chart: NOAA charted groin, a jetty / riprap in the 14 ft range, prime in spring. Time it for early morning. 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 groin (14 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 10 to 34 ft | dawn | NOAA charted groin (14 ft) | 1/2-1 oz tog jig + crab |
| Fall | 7 to 34 ft | midday | NOAA charted groin (14 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 10 to 34 ft | midday | NOAA charted groin (14 ft) | Heavy jig + crab on deep structure |
Structure-wise the chart holds 38 features, led in depth by NOAA charted pier at roughly 15 ft.

South Oyster Bay is about 34 ft (10 m) deep at its deepest point. The depth chart is built from real agency bathymetry referenced to NAVD88; directly measured coverage remains distinguished from source interpolation. The contours reflect measured and quality-assessed source depths.
Anglers target striped bass, bluefish, summer flounder (fluke), black sea bass, tautog (blackfish) on South Oyster Bay.
Surveyed channel edge is the top-rated area: a drop-off in about 9 ft of water that rates prime for summer flounder (fluke) in summer. Every other rated spot, per species and season, is on the map above.
For striped bass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
