221-acre Pocasset 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 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. Below is the species-by-species picture, pulled from the same data the map uses.
Pocasset Harbor maps at 221 acres behind 5 miles of shoreline, with 2 islands in the mix. A development index of 2.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 90% of the surface — that's where the groceries are. Call it 1.1 mi long by 0.7 mi wide at the broadest reach. If the bite dies, Dicks Pond is 5 mi to the north.
Spring puts striped bass in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 7 to 22 ft, wintering in 7 to 22 ft. Summer striped bass concentrate at Surveyed channel edge, a prime-rated drop-off around 12 ft. Warm-month bites cluster around early morning and the evening. A flutter spoon (deep) or an umbrella rig (trolled) covers the summer program.
| 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 22 ft | dawn & dusk | Surveyed channel edge (12 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 6 to 22 ft | dawn & dusk | Surveyed channel edge (12 ft) | Topwater walker, Jerkbait |
| Winter | 7 to 22 ft | midday | Surveyed channel edge (12 ft) | Alabama rig (slow), Flutter spoon |
When the water first warms, bluefish slide up into 3 to 20 ft. By summer they slide out to 4 to 22 ft, and by winter most fish are in 7 to 22 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 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 20 ft | dawn & dusk | Surveyed channel edge (12 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 4 to 22 ft | dawn & dusk | Surveyed channel edge (12 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 22 ft | dawn & midday | Surveyed channel edge (12 ft) | Pencil popper, Big metal |
| Winter | 7 to 22 ft | midday | Surveyed channel edge (12 ft) | Metal jig worked slow (southern waters) |
Start shallow in spring: summer flounder (fluke) sit in 4 to 22 ft that time of year. They don't go far with the seasons — 5 to 22 ft covers summer, 7 to 22 ft covers winter. The spot to know is Surveyed channel edge, a drop-off in about 12 ft of water that rates prime for summer flounder (fluke) in summer. Warm-month bites cluster around midday and early morning. Throw a bucktail (1-3 oz by drift speed) or a gulp grub on jighead until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 22 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 5 to 22 ft | midday & dawn | Surveyed channel edge (12 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 6 to 22 ft | midday | Surveyed channel edge (12 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 7 to 22 ft | midday | Surveyed channel edge (12 ft) | Slow bottom rig + strip |
Spring puts black sea bass in skinny water — 6 to 22 ft is the zone. Summer fish stay in 6 to 22 ft, and winter fish hold in 7 to 22 ft. Spring black sea bass concentrate at NOAA charted underwater rock, a prime-rated rock pile around 6 ft. Warm-month bites cluster around midday and early morning. A bucktail + grub or a diamond jig + squid teaser covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 22 ft | midday & dawn | NOAA charted underwater rock (6 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 6 to 22 ft | midday & dawn | NOAA charted underwater rock (6 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 6 to 22 ft | midday | NOAA charted underwater rock (6 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 7 to 22 ft | midday | NOAA charted underwater rock (9 ft) | Heavy hi-lo rig on deep wrecks |
Spring tautog (blackfish) on Pocasset Harbor hold shallow, usually 4 to 22 ft. Depth-wise the year is flat: 6 to 22 ft in summer, 7 to 22 ft once it turns cold. Put NOAA charted underwater rock first on the milk run — a rock pile near 5 ft that grades prime for spring. The feeding windows run 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 22 ft | midday & dawn | NOAA charted underwater rock (5 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 6 to 22 ft | dawn | NOAA charted underwater rock (6 ft) | 1/2-1 oz tog jig + crab |
| Fall | 4 to 22 ft | midday | NOAA charted underwater rock (5 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 7 to 22 ft | midday | NOAA charted underwater rock (9 ft) | Heavy jig + crab on deep structure |
Count 25 structure marks on this chart. The deepest, NOAA charted underwater rock, sits near 13 ft.

Pocasset Harbor 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 Pocasset 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. Open the map above to see every rated 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.
