13-acre Great Ledge Cove fishing map with NOAA BlueTopo survey contours (100% measured, 100% assessed), source-traceable coastal structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 40 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. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 13 acres wrapped in 0.6 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 53% of the water is 15 ft or less, the band where the food chain lives. If the bite dies, Dorseys Cove is 0 mi to the southwest.
Spring puts striped bass in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 12 to 40 ft; cold water stacks them in 12 to 40 ft. Surveyed channel edge is the standout, a drop-off at roughly 15 ft, rated good for summer striped bass. Plan around early morning and the evening in the warm months. A topwater walker at low light or a paddletail on a light jig covers the summer program.
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 (15 ft) | 3-6 inch paddletail, Suspending minnow plug |
| Summer | 12 to 40 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Surveyed channel edge (15 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (15 ft) | Pencil popper, Baitfish swimbait |
| Winter | 12 to 40 ft chart-limited; documented 20 to 50 ft | midday | Surveyed channel edge (15 ft) | Slow paddletail, Bucktail near bottom |
When the water first warms, bluefish slide up into 3 to 20 ft. Summer is a 5 to 30 ft game here, winter a 15 to 40 ft one. Start at Surveyed channel edge. It's a drop-off holding about 15 ft of water and rates good come summer. The feeding windows run 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 (15 ft) | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (15 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (15 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | open water | Metal jig worked slow (southern waters) |
Start shallow in spring: atlantic mackerel sit in 4 to 40 ft that time of year. They don't go far with the seasons — 8 to 40 ft covers summer, 10 to 40 ft covers winter. Top water on the chart: Surveyed channel edge, a drop-off in the 15 ft range, good in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a feather rig or a small vertical jig until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 40 ft chart-limited; documented 5 to 45 ft | dawn & dusk | Surveyed channel edge (15 ft) | Mackerel feather rig, Small silver jig |
| Summer | 8 to 40 ft chart-limited; documented 15 to 80 ft | dawn & dusk | Surveyed channel edge (15 ft) | Feather rig, Small vertical jig |
| Fall | 6 to 40 ft chart-limited; documented 10 to 65 ft | dawn & dusk | Surveyed channel edge (15 ft) | Compact silver jig, Sparse feather rig |
| Winter | 10 to 40 ft chart-limited; documented 30 to 120 ft | midday | Surveyed channel edge (15 ft) | Small deep jig |
The spring pattern is a shallow one: atlantic cod in 8 to 40 ft. The depth story barely changes: 10 to 40 ft through summer, 9 to 40 ft in winter. Top water on the chart: NOAA charted rock bottom, a hard bottom in the 5 ft range, prime in fall. Time it for early morning. Summer baits: a heavy metal jig or a large soft-plastic jig gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 40 ft chart-limited; documented 20 to 100 ft | dawn | NOAA charted rock bottom (5 ft) | Diamond jig, Heavy bucktail |
| Summer | 10 to 40 ft chart-limited; documented 45 to 180 ft | dawn | NOAA charted rock bottom (5 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 7 to 40 ft chart-limited; documented 25 to 140 ft | dawn | NOAA charted rock bottom (5 ft) | Diamond jig, Bucktail with teaser |
| Winter | 9 to 40 ft chart-limited; documented 50 to 220 ft | midday | NOAA charted rock bottom (5 ft) | Heavy vertical jig |
Come spring, look for atlantic herring tight to the bank in 5 to 25 ft. They move out to 12 to 40 ft in summer and finish the year down in 12 to 40 ft. If you only fish one area, make it NOAA charted pier: a dock line around 12 ft that scores prime in spring. Best bite is early morning and the evening. A herring feather rig or a small silver jig is the honest summer answer here.

Spring puts winter flounder in skinny water — 2 to 18 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 3 to 20 ft. Spring winter flounder concentrate at NOAA charted pier, a good-rated dock line around 12 ft. Warm-month bites cluster around early morning. A light scented jig worked slowly covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft | midday & dawn | NOAA charted pier (12 ft) | Small bucktail tipped with worm, Scented grub on a light jig |
| Summer | 8 to 30 ft | dawn | Surveyed channel edge (15 ft) | Light scented jig worked slowly |
| Fall | 6 to 25 ft | midday | Surveyed channel edge (15 ft) | Small bucktail + worm, Scented bottom jig |
| Winter | 3 to 20 ft | midday | Surveyed channel edge (15 ft) | Small bucktail tipped with worm |
5 pieces of structure are mapped here — Surveyed channel edge, around 15 ft, is the deepest of them.

Great Ledge Cove is about 40 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, atlantic mackerel, atlantic cod, atlantic herring, winter flounder on Great Ledge 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 rock bottom is the top-rated area: a hard bottom in about 5 ft of water that rates prime for atlantic cod in fall. 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 Great Ledge 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.
