243-acre Pettys Bight fishing map with NOAA BlueTopo survey contours (99.51% measured, 100% assessed), source-traceable coastal structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 43 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.
The drawn water covers 243 acres wrapped in 3.3 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 29% of this chart. Figure 1.4 mi of water from one end to the other, 0.5 mi at the beam. Its nearest charted neighbour, Coecles Harbor, is 6 mi to the south.
In spring, striped bass run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 13 to 43 ft before dropping to 13 to 43 ft for winter. Summer striped bass concentrate at Surveyed channel edge, a prime-rated drop-off around 20 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a flutter spoon (deep) or an umbrella rig (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (20 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 13 to 43 ft | dawn & dusk | Surveyed channel edge (20 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (20 ft) | Topwater walker, Jerkbait |
| Winter | 13 to 43 ft | midday | Surveyed channel edge (20 ft) | Alabama rig (slow), Flutter spoon |
Come spring, look for bluefish tight to the bank in 3 to 20 ft. They move out to 5 to 30 ft in summer and finish the year down in 15 to 40 ft. If you only fish one area, make it NOAA BlueTopo measured channel shoulder: a gravel shoal around 24 ft that scores prime in summer. Best bite is early morning and the evening. A popper (early/late) or a metal jigs in the rips is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Surveyed channel edge (20 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | NOAA BlueTopo measured channel shoulder (24 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | NOAA BlueTopo measured channel shoulder (24 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | Surveyed channel edge (20 ft) | Metal jig worked slow (southern waters) |
The spring pattern is a shallow one: summer flounder (fluke) in 5 to 25 ft. Midsummer fish sit out in 8 to 35 ft before dropping to 13 to 43 ft for winter. The spot to know is Surveyed channel edge, a drop-off in about 20 ft of water that rates prime for summer flounder (fluke) in summer. Plan around midday and early morning in the warm months. Summer baits: a bucktail (1-3 oz by drift speed) or a gulp grub on jighead gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Surveyed channel edge (20 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 8 to 35 ft | midday & dawn | Surveyed channel edge (20 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 11 to 43 ft | midday | Surveyed channel edge (20 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 13 to 43 ft | midday | Surveyed channel edge (20 ft) | Slow bottom rig + strip |
In spring, black sea bass run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 11 to 43 ft before dropping to 13 to 43 ft for winter. Spring black sea bass concentrate at NOAA charted underwater rock, a prime-rated rock pile around 25 ft. Fish it in midday and early morning and you'll meet the bite. You won't need more than a bucktail + grub or a diamond jig + squid teaser most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | midday & dawn | NOAA charted underwater rock (25 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 11 to 43 ft | midday & dawn | NOAA charted underwater rock (25 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 11 to 43 ft | midday | NOAA charted underwater rock (25 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 13 to 43 ft | midday | NOAA charted underwater rock (25 ft) | Heavy hi-lo rig on deep wrecks |
Early season tautog (blackfish) use the shallows, holding in 5 to 25 ft. Expect a summer slide to 10 to 35 ft, then a winter hold in 13 to 43 ft. Put NOAA charted underwater rock first on the milk run — a rock pile near 7 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a 1/2-1 oz tog jig + crab and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | NOAA charted underwater rock (7 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 10 to 35 ft | dawn | NOAA charted underwater rock (25 ft) | 1/2-1 oz tog jig + crab |
| Fall | 9 to 43 ft | midday | NOAA charted underwater rock (25 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 13 to 43 ft | midday | NOAA charted underwater rock (25 ft) | Heavy jig + crab on deep structure |

Pettys Bight is about 43 ft (13 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 Pettys Bight.
Surveyed channel edge is the top-rated area: a drop-off in about 20 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.
Fishing on Pettys Bight is regulated by the New York DEC (saltwater fishing). Check the official New York regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
