2,277-acre Captain Harbor fishing map with NOAA BlueTopo survey contours (97.41% measured, 99.52% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 41 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.
Traced from the shoreline, Captain Harbor runs 2,275 acres with 17.3 miles of edge, broken up by 18 islands. 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. The shallow band under 15 ft claims about 58% of the surface — that's where the groceries are. End to end it runs roughly 4.1 mi, about 1.9 mi across. Closest neighbour on DepthScout: Port Chester Harbor, 2 mi southwest of here.
When the water first warms, striped bass slide up into 5 to 20 ft. Summer is a 12 to 41 ft game here, winter a 12 to 41 ft one. Start at Surveyed channel edge. It's a drop-off holding about 34 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 | 12 to 41 ft | dawn & dusk | Surveyed channel edge (34 ft) | Flutter spoon (deep), Umbrella rig (trolled) |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (34 ft) | Topwater walker, Jerkbait |
| Winter | 12 to 41 ft | midday | Surveyed channel edge (34 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, 5 to 30 ft, and winter fish settle into 15 to 40 ft. The spot to know is Surveyed channel edge, a drop-off in about 22 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 (20 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (22 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Shallow feeding flat (20 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | Surveyed channel edge (34 ft) | Metal jig worked slow (southern waters) |
When the water first warms, summer flounder (fluke) slide up into 5 to 25 ft. By summer they slide out to 8 to 35 ft, and by winter most fish are in 12 to 41 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 34 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 25 ft | midday & dawn | Surveyed channel edge (22 ft) | Bucktail + Gulp swimming mullet, Hi-lo rig + squid strip |
| Summer | 8 to 35 ft | midday & dawn | Surveyed channel edge (34 ft) | Bucktail (1-3 oz by drift speed), Gulp grub on jighead |
| Fall | 11 to 41 ft | midday | Surveyed channel edge (34 ft) | Heavier bucktail on the lumps, Big Gulp 6" grub |
| Winter | 12 to 41 ft | midday | Surveyed channel edge (34 ft) | Slow bottom rig + strip |
When the water first warms, black sea bass slide up into 10 to 40 ft. Summer is a 10 to 41 ft game here, winter a 12 to 41 ft one. Start at NOAA charted underwater rock. It's a rock pile holding about 11 ft of water and rates prime come spring. 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 | 10 to 40 ft | midday & dawn | NOAA charted underwater rock (11 ft) | Hi-lo rig + squid, 1-2 oz bucktail + Gulp |
| Summer | 10 to 41 ft | midday & dawn | NOAA charted underwater rock (11 ft) | Bucktail + grub, Diamond jig + squid teaser |
| Fall | 10 to 41 ft | midday | NOAA charted underwater rock (11 ft) | 3-4 oz vertical jig (deep), Double-teaser rig |
| Winter | 12 to 41 ft | midday | Hitchcock Rock (13 ft) | Heavy hi-lo rig on deep wrecks |
Spring puts tautog (blackfish) in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 10 to 35 ft; cold water stacks them in 12 to 41 ft. Dangerous NOAA charted wreck is the standout, a wreck at roughly 8 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 25 ft | midday & dawn | Dangerous NOAA charted wreck (8 ft) | Tog jig + green crab half, Bare jig + clam (early) |
| Summer | 10 to 35 ft | dawn | Dangerous NOAA charted wreck (17 ft) | 1/2-1 oz tog jig + crab |
| Fall | 8 to 41 ft | midday | Dangerous NOAA charted wreck (8 ft) | Tog jig + whole green crab, Old-school rig + double crab (deep) |
| Winter | 12 to 41 ft | midday | Dangerous NOAA charted wreck (17 ft) | Heavy jig + crab on deep structure |

Captain Harbor is about 41 ft (12 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 Captain Harbor.
Surveyed channel edge is the top-rated area: a drop-off in about 34 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.
Fishing on Captain Harbor is regulated by the Connecticut DEEP (marine fishing). Check the official Connecticut regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
