914-acre Madaket Harbor fishing map with NOAA BlueTopo survey contours (100% measured, 100% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 24 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. What the data behind the map says about each species, season by season:
Drawn out, this is 913 acres of water rimmed by 7.3 miles of bank — 2 islands included. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. The shallow band under 15 ft claims about 93% of the surface — that's where the groceries are. End to end it runs roughly 2 mi, about 1.1 mi across. The nearest mapped water is Nantucket Harbor, 7 mi to the east.
When the water first warms, striped bass slide up into 5 to 20 ft. Summer is a 7 to 24 ft game here, winter a 7 to 24 ft one. Start at Surveyed channel edge. It's a drop-off holding about 12 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a flutter spoon (deep) or an umbrella rig (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (12 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 7 to 24 ft | dawn & dusk | Surveyed channel edge (12 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 7 to 24 ft | dawn & dusk | Surveyed channel edge (12 ft) | Topwater walker, Jerkbait |
| Winter | 7 to 24 ft | midday | Surveyed channel edge (12 ft) | Alabama rig (slow), Flutter spoon |
Start shallow in spring: bluefish sit in 3 to 20 ft that time of year. Summer pushes them deeper, 4 to 24 ft, and winter fish settle into 7 to 24 ft. The spot to know is Surveyed channel edge, a drop-off in about 12 ft of water that rates prime for bluefish in summer. Warm-month bites cluster around early morning and the evening. Throw a popper (early/late) or a metal jigs in the rips until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Shallow feeding flat (18 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 4 to 24 ft | dawn & dusk | Surveyed channel edge (12 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 24 ft | dawn & midday | Shallow feeding flat (18 ft) | Pencil popper, Big metal |
| Winter | 7 to 24 ft | midday | Surveyed channel edge (12 ft) | Metal jig worked slow (southern waters) |
When the water first warms, summer flounder (fluke) slide up into 5 to 24 ft. There's no big seasonal slide here — summer means 5 to 24 ft, winter 7 to 24 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 12 ft that scores prime in summer. In summer the feeding windows fall in midday and early morning. Keep a bucktail (1-3 oz by drift speed) or a gulp grub on jighead rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 24 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 5 to 24 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 6 to 24 ft | midday | Surveyed channel edge (12 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 7 to 24 ft | midday | Surveyed channel edge (12 ft) | Slow bottom rig + strip |
When the water first warms, black sea bass slide up into 6 to 24 ft. There's no big seasonal slide here — summer means 6 to 24 ft, winter 7 to 24 ft. Start at Surveyed channel edge. It's a drop-off holding about 12 ft of water and rates prime come summer. The feeding windows run midday and early morning. Keep a bucktail + grub or a diamond jig + squid teaser rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 24 ft | midday & dawn | NOAA charted underwater rock (2 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 6 to 24 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 6 to 24 ft | midday | Surveyed channel edge (12 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 7 to 24 ft | midday | NOAA charted underwater rock (2 ft) | Heavy hi-lo rig on deep wrecks |
Spring puts tautog (blackfish) in skinny water — 5 to 24 ft is the zone. Summer fish stay in 7 to 24 ft, and winter fish hold in 7 to 24 ft. NOAA charted underwater rock is the standout, a rock pile at roughly 2 ft, rated prime for spring tautog (blackfish). Plan around early morning in the warm months. A 1/2-1 oz tog jig + crab covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 24 ft | midday & dawn | NOAA charted underwater rock (2 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 7 to 24 ft | dawn | NOAA charted underwater rock (2 ft) | 1/2-1 oz tog jig + crab |
| Fall | 5 to 24 ft | midday | NOAA charted underwater rock (2 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 7 to 24 ft | midday | NOAA charted underwater rock (2 ft) | Heavy jig + crab on deep structure |

Madaket Harbor is about 24 ft (7 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 Madaket Harbor.
Surveyed channel edge is the top-rated area: a drop-off in about 12 ft of water that rates prime for summer flounder (fluke) in summer. 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.
