1,643-acre Nasketucket Bay fishing map with NOAA BlueTopo survey contours (97.06% measured, 100% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 22 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.
Nasketucket Bay maps at 1,641 acres behind 14.8 miles of shoreline — 9 islands included. A development index of 2.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. Littoral water — the productive band under ~15 ft — makes up 83% of this chart. Call it 2.8 mi long by 2 mi wide at the broadest reach. If the bite dies, Buzzards Bay is 3 mi to the southeast.
Start shallow in spring: striped bass sit in 5 to 20 ft that time of year. Warm water sends them out to 7 to 22 ft; cold water stacks them in 7 to 22 ft. Top water on the chart: Surveyed channel edge, a drop-off in the 17 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a flutter spoon (deep) or an umbrella rig (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (17 ft) | Bucktail jig + trailer, Walking topwater (dawn) |
| Summer | 7 to 22 ft | dawn & dusk | Surveyed channel edge (17 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 6 to 22 ft | dawn & dusk | Surveyed channel edge (17 ft) | Topwater walker, Jerkbait |
| Winter | 7 to 22 ft | midday | Surveyed channel edge (17 ft) | Alabama rig (slow), Flutter spoon |
Early season bluefish use the shallows, holding in 3 to 20 ft. Summer is a 4 to 22 ft game here, winter a 7 to 22 ft one. The chart's best answer is Surveyed channel edge — drop-off, 17 ft, prime for summer. Best bite is early morning and the evening. Tie on a popper (early/late) or a metal jigs in the rips and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | Surveyed channel edge (17 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 4 to 22 ft | dawn & dusk | Surveyed channel edge (17 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 22 ft | dawn & midday | Surveyed channel edge (17 ft) | Pencil popper, Big metal |
| Winter | 7 to 22 ft | midday | Surveyed channel edge (17 ft) | Metal jig worked slow (southern waters) |
Spring puts summer flounder (fluke) in skinny water — 4 to 22 ft is the zone. Summer fish stay in 5 to 22 ft, and winter fish hold in 7 to 22 ft. Surveyed channel edge is the standout, a drop-off at roughly 17 ft, rated prime for summer summer flounder (fluke). Plan around midday and early morning in the warm months. A bucktail (1-3 oz by drift speed) or a gulp grub on jighead covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 22 ft | midday & dawn | Surveyed channel edge (17 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 5 to 22 ft | midday & dawn | Surveyed channel edge (17 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 6 to 22 ft | midday | Surveyed channel edge (17 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 7 to 22 ft | midday | Surveyed channel edge (17 ft) | Slow bottom rig + strip |
Start shallow in spring: black sea bass sit in 6 to 22 ft that time of year. They don't go far with the seasons — 6 to 22 ft covers summer, 7 to 22 ft covers winter. Top water on the chart: NOAA charted underwater rock, a rock pile in the 7 ft range, prime in spring. Fish it in midday and early morning and you'll meet the bite. Throw a bucktail + grub or a diamond jig + squid teaser until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 22 ft | midday & dawn | NOAA charted underwater rock (7 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 6 to 22 ft | midday & dawn | NOAA charted underwater rock (7 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 6 to 22 ft | midday | NOAA charted underwater rock (7 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 7 to 22 ft | midday | NOAA charted underwater rock (7 ft) | Heavy hi-lo rig on deep wrecks |
When the water first warms, tautog (blackfish) slide up into 4 to 22 ft. There's no big seasonal slide here — summer means 6 to 22 ft, winter 7 to 22 ft. If you only fish one area, make it NOAA charted underwater rock: a rock pile around 7 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a 1/2-1 oz tog jig + crab rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 22 ft | midday & dawn | NOAA charted underwater rock (7 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 6 to 22 ft | dawn | NOAA charted underwater rock (7 ft) | 1/2-1 oz tog jig + crab |
| Fall | 4 to 22 ft | midday | NOAA charted underwater rock (7 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 7 to 22 ft | midday | NOAA charted underwater rock (7 ft) | Heavy jig + crab on deep structure |

Nasketucket Bay is about 22 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 Nasketucket Bay.
Surveyed channel edge is the top-rated area: a drop-off in about 17 ft of water that rates prime for summer flounder (fluke) in summer. The map above holds the full rated-spot list for every 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.
