1,156-acre Coecles Harbor fishing map with NOAA BlueTopo survey contours (98.46% measured, 100% 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. Here's the year, species by species, as the scoring engine sees it.
On the chart, Coecles Harbor draws 1,154 acres inside 11.3 miles of shoreline, broken up by 2 islands. An index of 2.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 96% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 2.6 mi with a 1.5-mi widest point. Closest neighbour on DepthScout: Fresh Pond (Shelter Island), 2 mi southwest of here.
Early season striped bass use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 28 ft, then a winter hold in 8 to 28 ft. Put Surveyed channel edge first on the milk run — a drop-off near 12 ft that grades good for summer. In summer the feeding windows fall in early morning and the evening. Tie on a topwater walker at low light or a paddletail on a light jig and you're in the game.
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 20 ft | dawn & dusk | Surveyed channel edge (12 ft) | 3-6 inch paddletail, Suspending minnow plug |
| Summer | 8 to 28 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Surveyed channel edge (12 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 8 to 28 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Surveyed channel edge (12 ft) | Pencil popper, Baitfish swimbait |
| Winter | 8 to 28 ft chart-limited; documented 20 to 50 ft | midday | Surveyed channel edge (12 ft) | Slow paddletail, Bucktail near bottom |
In spring, bluefish run shallow here, mostly 3 to 20 ft. Midsummer fish sit out in 5 to 28 ft before dropping to 8 to 28 ft for winter. Summer bluefish concentrate at Surveyed channel edge, a good-rated drop-off around 12 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a popper (early/late) or a metal jigs in the rips most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Surveyed channel edge (12 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 28 ft chart-limited; documented 5 to 30 ft | dawn & dusk | Surveyed channel edge (12 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (12 ft) | Pencil popper, Big metal |
| Winter | 8 to 28 ft chart-limited; documented 15 to 40 ft | midday | open water | Metal jig worked slow (southern waters) |
Spring summer flounder (fluke) on Coecles Harbor hold shallow, usually 5 to 25 ft. They move out to 6 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 12 ft that grades prime for summer. The feeding windows run midday and early morning. The summer box starts with a bucktail (1-3 oz by drift speed) or a gulp grub on jighead.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 6 to 28 ft chart-limited; documented 8 to 35 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 7 to 28 ft chart-limited; documented 12 to 45 ft | midday | Surveyed channel edge (12 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 8 to 28 ft chart-limited; documented 20 to 60 ft | midday | Surveyed channel edge (12 ft) | Slow bottom rig + strip |
Early season black sea bass use the shallows, holding in 7 to 28 ft. Even in summer they hold at 7 to 28 ft; winter keeps them in 8 to 28 ft. Put NOAA charted underwater rock first on the milk run — a rock pile near 10 ft that grades prime for spring. In summer the feeding windows fall in midday and early morning. Tie on a bucktail + grub or a diamond jig + squid teaser and you're in the game.

| Spring | 7 to 28 ft chart-limited; documented 10 to 40 ft | midday & dawn | NOAA charted underwater rock (10 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 7 to 28 ft chart-limited; documented 15 to 60 ft | midday & dawn | NOAA charted underwater rock (10 ft) | Bucktail + grub, Diamond jig + squid teaser |

| Winter | 8 to 28 ft chart-limited; documented 40 to 100 ft | midday | NOAA charted underwater rock (10 ft) | Heavy hi-lo rig on deep wrecks |
Start shallow in spring: tautog (blackfish) sit in 5 to 25 ft that time of year. Summer pushes them deeper, 8 to 28 ft, and winter fish settle into 8 to 28 ft. The spot to know is NOAA charted underwater rock, a rock pile in about 10 ft of water that rates prime for tautog (blackfish) in spring. Warm-month bites cluster around early morning. Throw a 1/2-1 oz tog jig + crab until the fish tell you otherwise.

Spring scup (porgy) on Coecles Harbor hold shallow, usually 5 to 25 ft. By summer they slide out to 5 to 28 ft, and by winter most fish are in 7 to 28 ft. The chart's best answer is NOAA charted underwater rock — rock pile, 10 ft, prime for spring. Prime time lands in midday and early morning. The summer box starts with a hi-lo porgy rig or a micro metal jig.

Coecles Harbor is about 28 ft (9 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 Coecles 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 underwater rock is the top-rated area: a rock pile in about 10 ft of water that rates prime for black sea bass in spring. 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 Coecles Harbor 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.
