464-acre Cutchogue Harbor fishing map with NOAA BlueTopo survey contours (100% measured and assessed), source-traceable fishing spots, Peconic Estuary fish and forage evidence, an exact public boat ramp, habitat guidance and current New York rules. The water tops out around 19 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.
Cutchogue Harbor maps at 463 acres behind 6.8 miles of shoreline — one island included. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. About 98% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 1.6 mi, about 0.8 mi across. Its nearest charted neighbour, Marratooka Lake, is 3 mi to the west.
Spring puts striped bass in skinny water — 5 to 19 ft is the zone. Summer fish stay in 6 to 19 ft, and winter fish hold in 6 to 19 ft. Surveyed channel edge 4 is the standout, a drop-off at roughly 10 ft, rated good for summer striped bass. Plan around early morning and the evening in the warm months. A topwater walker at low light or a paddletail on a light jig covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 19 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Surveyed channel edge 4 (10 ft) | 3-6 inch paddletail, Suspending minnow plug |
| Summer | 6 to 19 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Surveyed channel edge 4 (10 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 5 to 19 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Surveyed channel edge 4 (10 ft) | Pencil popper, Baitfish swimbait |
| Winter | 6 to 19 ft chart-limited; documented 20 to 50 ft | midday | Surveyed channel edge 4 (10 ft) | Slow paddletail, Bucktail near bottom |
When the water first warms, bluefish slide up into 3 to 19 ft. There's no big seasonal slide here — summer means 3 to 19 ft, winter 6 to 19 ft. Start at Surveyed channel edge 4. It's a drop-off holding about 10 ft of water and rates good come summer. The feeding windows run early morning and the evening. Keep a popper (early/late) or a metal jigs in the rips rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 19 ft chart-limited; documented 3 to 20 ft | dawn & dusk | Surveyed channel edge 4 (10 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 3 to 19 ft chart-limited; documented 5 to 30 ft | dawn & dusk | Surveyed channel edge 4 (10 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 2 to 19 ft chart-limited; documented 3 to 25 ft | dawn & midday | Surveyed channel edge 4 (10 ft) | Pencil popper, Big metal |
| Winter | 6 to 19 ft chart-limited; documented 15 to 40 ft | midday | open water | Metal jig worked slow (southern waters) |
Start shallow in spring: summer flounder (fluke) sit in 4 to 19 ft that time of year. They don't go far with the seasons — 4 to 19 ft covers summer, 6 to 19 ft covers winter. Top water on the chart: Surveyed channel edge 4, a drop-off in the 10 ft range, prime in summer. Fish it in midday and early morning and you'll meet the bite. Throw a bucktail (1-3 oz by drift speed) or a gulp grub on jighead until the fish tell you otherwise.

|---|---|---|---|---|
| Spring | 4 to 19 ft chart-limited; documented 5 to 25 ft | midday & dawn | Surveyed channel edge 4 (10 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 4 to 19 ft chart-limited; documented 8 to 35 ft | midday & dawn | Surveyed channel edge 4 (10 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 5 to 19 ft chart-limited; documented 12 to 45 ft | midday | Surveyed channel edge 4 (10 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |

Spring puts black sea bass in skinny water — 5 to 19 ft is the zone. Summer fish stay in 5 to 19 ft, and winter fish hold in 6 to 19 ft. NOAA charted wreck is the standout, a wreck at roughly 6 ft, rated prime for spring black sea bass. Plan around midday and early morning in the warm months. A bucktail + grub or a diamond jig + squid teaser covers the summer program.

| Spring | 5 to 19 ft chart-limited; documented 10 to 40 ft | midday & dawn | NOAA charted wreck (6 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 5 to 19 ft chart-limited; documented 15 to 60 ft | midday & dawn | NOAA charted wreck (6 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 5 to 19 ft chart-limited; documented 20 to 80 ft | midday | NOAA charted wreck (6 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 6 to 19 ft chart-limited; documented 40 to 100 ft | midday | NOAA charted wreck (6 ft) | Heavy hi-lo rig on deep wrecks |
Spring tautog (blackfish) on Cutchogue Harbor hold shallow, usually 4 to 19 ft. Depth-wise the year is flat: 5 to 19 ft in summer, 6 to 19 ft once it turns cold. The chart's best answer is NOAA charted wreck — wreck, 6 ft, prime for spring. Prime time lands in early morning. The summer box starts with a 1/2-1 oz tog jig + crab.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 19 ft chart-limited; documented 5 to 25 ft | midday & dawn | NOAA charted wreck (6 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 5 to 19 ft chart-limited; documented 10 to 35 ft | dawn | NOAA charted wreck (6 ft) | 1/2-1 oz tog jig + crab |
| Fall | 4 to 19 ft chart-limited; documented 10 to 50 ft | midday | NOAA charted wreck (6 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 6 to 19 ft chart-limited; documented 30 to 70 ft | midday | NOAA charted wreck (6 ft) | Heavy jig + crab on deep structure |
In spring, scup (porgy) run shallow here, mostly 4 to 19 ft. Summer keeps them at 3 to 19 ft, and they winter in 5 to 19 ft. Spring scup (porgy) concentrate at NOAA charted underwater rock, a prime-rated rock pile around 4 ft. Fish it in midday and early morning and you'll meet the bite. You won't need more than a hi-lo porgy rig or a micro metal jig most summer days.

Cutchogue Harbor is about 19 ft (6 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), scup (porgy), winter flounder on Cutchogue Harbor. The list combines the water's survey records with habitat-filtered species from broader official evidence; those additions are plausible occurrences, not exact-water abundance or guaranteed catches.
NOAA charted wreck is the top-rated area: a wreck in about 6 ft of water that rates prime for tautog (blackfish) in spring. The interactive chart above rates every spot for each species and season.
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.
