580-acre Schoodic Harbor fishing map with NOAA BlueTopo survey contours (89.1% measured, 100% assessed), charted rock and wreck structure, regional fish-survey occurrence, sourced forage timing and verified public access. The water tops out around 78 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 rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 579 acres wrapped in 5.2 miles of bank, with a single island in the mix. With a 1.5 development index there's bank structure worth casting at, in moderation. Roughly 14% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1.8 mi, about 1 mi across. Bunkers Harbor sits 1 mi north — the closest neighbouring chart.
Start shallow in spring: striped bass sit in 5 to 20 ft that time of year. Warm water sends them out to 25 to 60 ft; cold water stacks them in 20 to 50 ft. Top water on the chart: Surveyed channel edge, a drop-off in the 28 ft range, good in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a topwater walker at low light or a paddletail on a light jig 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 (22 ft) | 3-6 inch paddletail, Suspending minnow plug |
| Summer | 25 to 60 ft | dawn & dusk | Surveyed channel edge (28 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 10 to 35 ft | dawn & dusk | Surveyed channel edge (28 ft) | Pencil popper, Baitfish swimbait |
| Winter | 20 to 50 ft | midday | Surveyed channel edge (28 ft) | Slow paddletail, Bucktail near bottom |
Early season bluefish use the shallows, holding in 3 to 20 ft. Summer is a 5 to 30 ft game here, winter a 15 to 40 ft one. The chart's best answer is Surveyed channel edge — drop-off, 28 ft, good 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 | open water | Metal (Hopkins/Kastmaster), Pencil popper |
| Summer | 5 to 30 ft | dawn & dusk | Surveyed channel edge (28 ft) | Popper (early/late), Metal jigs in the rips |
| Fall | 3 to 25 ft | dawn & midday | Surveyed channel edge (22 ft) | Pencil popper, Big metal |
| Winter | 15 to 40 ft | midday | open water | Metal jig worked slow (southern waters) |
Spring puts atlantic mackerel in skinny water — 5 to 45 ft is the zone. Warm water sends them out to 15 to 78 ft; cold water stacks them in 20 to 78 ft. Surveyed channel edge is the standout, a drop-off at roughly 28 ft, rated good for summer atlantic mackerel. Plan around early morning and the evening in the warm months. A feather rig or a small vertical 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 45 ft | dawn & dusk | Surveyed channel edge (28 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 78 ft chart-limited; documented 15 to 80 ft | dawn & dusk | Surveyed channel edge (28 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Surveyed channel edge (28 ft) | Compact silver jig, Sparse feather rig |
| Winter | 20 to 78 ft chart-limited; documented 30 to 120 ft | midday | Surveyed channel edge (28 ft) | Small deep jig |
Spring puts atlantic cod in skinny water — 16 to 78 ft is the zone. Summer fish stay in 20 to 78 ft, and winter fish hold in 18 to 78 ft. Spring atlantic cod concentrate at NOAA charted underwater rock, a prime-rated rock pile around 22 ft. Warm-month bites cluster around early morning. A heavy metal jig or a large soft-plastic 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 | 16 to 78 ft chart-limited; documented 20 to 100 ft | dawn | NOAA charted underwater rock (22 ft) | Diamond jig, Heavy bucktail |
| Summer | 20 to 78 ft chart-limited; documented 45 to 180 ft | dawn | NOAA charted rock bottom (22 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 14 to 78 ft chart-limited; documented 25 to 140 ft | dawn | NOAA charted underwater rock (14 ft) | Diamond jig, Bucktail with teaser |
| Winter | 18 to 78 ft chart-limited; documented 50 to 220 ft | midday | NOAA charted rock bottom (22 ft) | Heavy vertical jig |
Spring atlantic herring on Schoodic Harbor hold shallow, usually 5 to 25 ft. They move out to 15 to 50 ft in summer and finish the year down in 20 to 60 ft. Put NOAA charted underwater rock first on the milk run — a rock pile near 14 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a herring feather rig or a small silver jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | NOAA charted underwater rock (14 ft) | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | Surveyed channel edge (28 ft) | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | Surveyed channel edge (28 ft) | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | Surveyed channel edge (28 ft) | Small silver jig, Sparse feather rig |
The spring pattern is a shallow one: winter flounder in 2 to 18 ft. As the season builds they drop to 8 to 30 ft, wintering in 3 to 20 ft. Top water on the chart: Surveyed channel edge, a drop-off in the 22 ft range, good in fall. Time it for early morning. Summer baits: a light scented jig worked slowly gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft | midday & dawn | NOAA charted underwater rock (14 ft) | Small bucktail tipped with worm, Scented grub on a light jig |
| Summer | 8 to 30 ft | dawn | Surveyed channel edge (28 ft) | Light scented jig worked slowly |
| Fall | 6 to 25 ft | midday | Surveyed channel edge (22 ft) | Small bucktail + worm, Scented bottom jig |
| Winter | 3 to 20 ft | midday | open water | Small bucktail tipped with worm |
The chart marks 39 structure features on Schoodic Harbor; the deepest is Surveyed channel edge at about 39 ft.

Schoodic Harbor is about 78 ft (24 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 Schoodic Harbor. 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 22 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 Schoodic Harbor 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.
