Rating depth structure for atlantic cod.

231-acre Flagg Cove fishing map with contributor-qualified CHS NONNA survey contours (88.24% measured, 95.72% assessed), four measured spots, nearby DFO cod, mackerel and forage evidence, working-harbour context, and current groundfish, mackerel and CSSP rules. The water tops out around 55 ft. The depth chart comes from CHS bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 231 acres wrapped in 3.6 miles of bank. With a 1.7 development index there's bank structure worth casting at, in moderation. 48% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 1 mi with a 0.6-mi widest point. If the bite dies, Eel Lake is 2 mi to the northwest.
Spring puts atlantic cod in skinny water — 11 to 55 ft is the zone. Summer fish stay in 14 to 55 ft, and winter fish hold in 13 to 55 ft. Flagg Cove surveyed deepest basin cell is the standout, a deep basin at roughly 55 ft, rated prime for winter atlantic cod. Plan around early morning in the warm months. 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 | 11 to 55 ft chart-limited; documented 20 to 100 ft | dawn | Flagg Cove northeastern surveyed entrance edge (16 ft) | Diamond jig, Heavy bucktail |
| Summer | 14 to 55 ft chart-limited; documented 45 to 180 ft | dawn | Flagg Cove surveyed deepest basin cell (55 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 10 to 55 ft chart-limited; documented 25 to 140 ft | dawn | Flagg Cove northeastern surveyed entrance edge (16 ft) | Diamond jig, Bucktail with teaser |
| Winter | 13 to 55 ft chart-limited; documented 50 to 220 ft | midday | Flagg Cove surveyed deepest basin cell (55 ft) | Heavy vertical jig |
Spring puts atlantic mackerel in skinny water — 5 to 45 ft is the zone. As the season builds they drop to 10 to 55 ft, wintering in 14 to 55 ft. Summer atlantic mackerel concentrate at Flagg Cove surveyed central basin, a prime-rated deep basin around 11 ft. Warm-month bites cluster around early morning and the evening. A feather rig or a small vertical jig covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Flagg Cove northeastern surveyed entrance edge (16 ft) | Mackerel feather rig, Small silver jig |
| Summer | 10 to 55 ft chart-limited; documented 15 to 80 ft | dawn & dusk | Flagg Cove surveyed central basin (11 ft) | Feather rig, Small vertical jig |
| Fall | 8 to 55 ft chart-limited; documented 10 to 65 ft | dawn & dusk | Flagg Cove surveyed central basin (11 ft) | Compact silver jig, Sparse feather rig |
| Winter | 14 to 55 ft chart-limited; documented 30 to 120 ft | midday | Flagg Cove surveyed deepest basin cell (55 ft) | Small deep jig |
The spring pattern is a shallow one: winter flounder in 2 to 18 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Flagg Cove northeastern surveyed entrance edge, a channel edge in about 16 ft of water that rates prime for winter flounder in spring. Plan around early morning in the warm months. 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 | Flagg Cove northeastern surveyed entrance edge (16 ft) | Small bucktail tipped with worm, Scented grub on a light jig |
| Summer | 8 to 30 ft | dawn | Flagg Cove surveyed central basin (11 ft) | Light scented jig worked slowly |
| Fall | 6 to 25 ft | midday | Flagg Cove northeastern surveyed entrance edge (16 ft) | Small bucktail + worm, Scented bottom jig |
| Winter | 3 to 20 ft | midday | Flagg Cove northeastern surveyed entrance edge (16 ft) | Small bucktail tipped with worm |
Start shallow in spring: striped bass sit in 5 to 20 ft that time of year. Summer pushes them deeper, 17 to 55 ft, and winter fish settle into 20 to 50 ft. The spot to know is Flagg Cove surveyed deepest basin cell, a deep basin in about 55 ft of water that rates prime for striped bass in summer. Warm-month bites cluster around early morning and the evening. 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 1 (18 ft) | 3-5 inch baitfish swimbait, Suspending minnow plug |
| Summer | 17 to 55 ft chart-limited; documented 25 to 60 ft | dawn & dusk | Flagg Cove surveyed deepest basin cell (55 ft) | Topwater walker at low light, Paddletail on a light jig |
| Fall | 10 to 35 ft | dawn & dusk | Flagg Cove surveyed central basin (11 ft) | Baitfish swimbait, Metal jig |
| Winter | 20 to 50 ft | midday | Flagg Cove surveyed deepest basin cell (55 ft) | Slow paddletail, Bucktail near bottom |

Flagg Cove is about 55 ft (17 m) deep at its deepest point. The depth chart comes from CHS bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target atlantic cod, atlantic mackerel, winter flounder, striped bass on Flagg 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.
Flagg Cove surveyed deepest basin cell is the top-rated area: a deep basin in about 55 ft of water that rates prime for atlantic cod in winter. Open the map above to see every rated spot for each species and season.
For atlantic cod, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
