325-acre Webb Cove 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 27 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. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 325 acres of water rimmed by 6.4 miles of bank, broken up by 5 islands. The 2.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 79% of this chart. Figure 1.2 mi of water from one end to the other, 0.9 mi at the beam. For a second option, Southeast Harbor lies 2 mi north.
Come spring, look for striped bass tight to the bank in 5 to 20 ft. Expect a summer slide to 8 to 27 ft, then a winter hold in 8 to 27 ft. Start at Surveyed channel edge. It's a drop-off holding about 14 ft of water and rates good come summer. Prime time lands in early morning and the evening. A topwater walker at low light or a paddletail on a light jig is the honest summer answer here.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Surveyed channel edge (14 ft) | 3-6 inch paddletail, Suspending minnow plug |
| Summer | 8 to 27 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Surveyed channel edge (14 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 8 to 27 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Surveyed channel edge (14 ft) | Pencil popper, Baitfish swimbait |
| Winter | 8 to 27 ft chart-limited; documented 20 to 50 ft | midday | Surveyed channel edge (14 ft) | Slow paddletail, Bucktail near bottom |
The spring pattern is a shallow one: bluefish in 3 to 20 ft. Midsummer fish sit out in 5 to 27 ft before dropping to 8 to 27 ft for winter. The spot to know is Surveyed channel edge, a drop-off in about 14 ft of water that rates good 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 (14 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 27 ft chart-limited; documented 5 to 30 ft | dawn & dusk | Surveyed channel edge (14 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (14 ft) | Pencil popper, Big metal |
| Winter | 8 to 27 ft chart-limited; documented 15 to 40 ft | midday | open water | Metal jig worked slow (southern waters) |
Come spring, look for atlantic mackerel tight to the bank in 3 to 27 ft. Through summer count on 5 to 27 ft; the winter hold is 7 to 27 ft. If you only fish one area, make it Surveyed channel edge: a drop-off around 14 ft that scores good in summer. Best bite is early morning and the evening. A feather rig or a small vertical jig is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 27 ft chart-limited; documented 5 to 45 ft | dawn & dusk | Surveyed channel edge (14 ft) | Mackerel feather rig, Small silver jig |
| Summer | 5 to 27 ft chart-limited; documented 15 to 80 ft | dawn & dusk | Surveyed channel edge (14 ft) | Feather rig, Small vertical jig |
| Fall | 4 to 27 ft chart-limited; documented 10 to 65 ft | dawn & dusk | Surveyed channel edge (14 ft) | Compact silver jig, Sparse feather rig |
| Winter | 7 to 27 ft chart-limited; documented 30 to 120 ft | midday | Surveyed channel edge (14 ft) | Small deep jig |
Early season atlantic cod use the shallows, holding in 5 to 27 ft. Even in summer they hold at 7 to 27 ft; winter keeps them in 6 to 27 ft. The chart's best answer is NOAA charted underwater rock — rock pile, 11 ft, prime for spring. Best bite is early morning. Tie on a heavy metal jig or a large soft-plastic jig and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 27 ft chart-limited; documented 20 to 100 ft | dawn | NOAA charted underwater rock (11 ft) | Diamond jig, Heavy bucktail |
| Summer | 7 to 27 ft chart-limited; documented 45 to 180 ft | dawn | NOAA charted underwater rock (11 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 5 to 27 ft chart-limited; documented 25 to 140 ft | dawn | NOAA charted underwater rock (11 ft) | Diamond jig, Bucktail with teaser |
| Winter | 6 to 27 ft chart-limited; documented 50 to 220 ft | midday | NOAA charted underwater rock (11 ft) | Heavy vertical jig |
Start shallow in spring: atlantic herring sit in 5 to 25 ft that time of year. Warm water sends them out to 8 to 27 ft; cold water stacks them in 8 to 27 ft. Top water on the chart: NOAA charted underwater rock, a rock pile in the 11 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a herring feather rig or a small silver jig until the fish tell you otherwise.

Early season winter flounder use the shallows, holding in 2 to 18 ft. Expect a summer slide to 7 to 27 ft, then a winter hold in 3 to 20 ft. Put Surveyed channel edge first on the milk run — a drop-off near 14 ft that grades good for spring. In summer the feeding windows fall in early morning. Tie on a light scented jig worked slowly and you're in the game.

Webb Cove is about 27 ft (8 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, atlantic mackerel, atlantic cod, atlantic herring, winter flounder on Webb Cove. The list combines the water's survey records with habitat-filtered species from broader official evidence; those additions are plausible occurrences, not exact-water abundance or guaranteed catches.
NOAA charted underwater rock is the top-rated area: a rock pile in about 11 ft of water that rates prime for atlantic cod in spring. Scroll up to the map for the complete spot list by 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 Webb Cove is regulated by the Maine DMR (saltwater recreational fishing). Check the official Maine regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
