77-acre Nobscusset 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 31 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, Nobscusset Harbor draws 77 acres inside 1.5 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. Roughly 39% of the water is 15 ft or less, the band where the food chain lives. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. For a second option, Walkers Pond lies 3 mi southeast.
Come spring, look for striped bass tight to the bank in 5 to 20 ft. Expect a summer slide to 9 to 31 ft, then a winter hold in 9 to 31 ft. Start at Surveyed channel edge. It's a drop-off holding about 16 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A flutter spoon (deep) or an umbrella rig (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (16 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 9 to 31 ft | dawn & dusk | Surveyed channel edge (16 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 9 to 31 ft | dawn & dusk | Surveyed channel edge (16 ft) | Topwater walker, Jerkbait |
| Winter | 9 to 31 ft | midday | Surveyed channel edge (16 ft) | Alabama rig (slow), Flutter spoon |
The spring pattern is a shallow one: bluefish in 3 to 20 ft. Midsummer fish sit out in 5 to 30 ft before dropping to 9 to 31 ft for winter. The spot to know is Surveyed channel edge, a drop-off in about 16 ft of water that rates prime for bluefish in summer. Plan around early morning and the evening in the warm months. Summer baits: a popper (early/late) or a metal jigs in the rips gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Surveyed channel edge (16 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (16 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (16 ft) | Pencil popper, Big metal |
| Winter | 9 to 31 ft | midday | Surveyed channel edge (16 ft) | Metal jig worked slow (southern waters) |
Come spring, look for summer flounder (fluke) tight to the bank in 5 to 25 ft. They move out to 7 to 31 ft in summer and finish the year down in 9 to 31 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 16 ft that scores prime in summer. Best bite is midday and early morning. A bucktail (1-3 oz by drift speed) or a gulp grub on jighead is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | midday & dawn | Surveyed channel edge (16 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 7 to 31 ft | midday & dawn | Surveyed channel edge (16 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 8 to 31 ft | midday | Surveyed channel edge (16 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 9 to 31 ft | midday | Surveyed channel edge (16 ft) | Slow bottom rig + strip |
Come spring, look for black sea bass tight to the bank in 8 to 31 ft. Through summer count on 8 to 31 ft; the winter hold is 9 to 31 ft. Start at NOAA charted underwater rock. It's a rock pile holding about 7 ft of water and rates prime come spring. Prime time lands in midday and early morning. A bucktail + grub or a diamond jig + squid teaser is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 31 ft | midday & dawn | NOAA charted underwater rock (7 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 8 to 31 ft | midday & dawn | NOAA charted underwater rock (7 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 8 to 31 ft | midday | NOAA charted underwater rock (7 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 9 to 31 ft | midday | NOAA charted underwater rock (7 ft) | Heavy hi-lo rig on deep wrecks |
In spring, tautog (blackfish) run shallow here, mostly 5 to 25 ft. Summer pushes them deeper, 9 to 31 ft, and winter fish settle into 9 to 31 ft. NOAA charted underwater rock is the standout, a rock pile at roughly 7 ft, rated prime for spring tautog (blackfish). Time it for early morning. You won't need more than a 1/2-1 oz tog jig + crab most summer days.
| 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 | 9 to 31 ft | dawn | NOAA charted underwater rock (7 ft) | 1/2-1 oz tog jig + crab |
| Fall | 6 to 31 ft | midday | NOAA charted underwater rock (7 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 9 to 31 ft | midday | NOAA charted underwater rock (7 ft) | Heavy jig + crab on deep structure |
Nobscusset Harbor carries 3 mapped structure features, topping out (or rather bottoming out) at Surveyed channel edge, about 16 ft down.

Nobscusset Harbor is about 31 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) on Nobscusset Harbor.
Surveyed channel edge is the top-rated area: a drop-off in about 16 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 Nobscusset Harbor is regulated by the Massachusetts DMF (recreational saltwater). Check the official Massachusetts regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
