Rating depth structure for atlantic mackerel.

1,717-acre Sheet Harbour fishing map with CHS NONNA survey contours (49.2% measured, 99.27% assessed), four measured spots, regional DFO cod, mackerel and forage evidence, an official water-arrival anchorage reference, and current groundfish, mackerel, CSSP, pilotage and port guidance. The water tops out around 72 ft. The depth chart comes from CHS bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Sheet Harbour runs 1,715 acres with 17 miles of edge, broken up by 2 islands. That shoreline is heavily fingered (development index 2.9) — bays, points and pockets everywhere, which multiplies the fishable edge. About 34% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 5.5 mi end to end and 1.6 mi across at its widest. The nearest mapped water is Grand Lake, 5 mi to the west.
When the water first warms, atlantic cod slide up into 14 to 72 ft. There's no big seasonal slide here — summer means 18 to 72 ft, winter 16 to 72 ft. If you only fish one area, make it Sheet Harbour surveyed entrance trough: a deep basin around 72 ft that scores prime in winter. In summer the feeding windows fall in early morning. Keep a heavy metal jig or a large soft-plastic jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 14 to 72 ft | dawn | Slab Point surveyed shoal-water edge (40 ft) | Diamond jig, Heavy bucktail |
| Summer | 18 to 72 ft | dawn | Sheet Harbour surveyed entrance trough (72 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 13 to 72 ft | dawn | Slab Point surveyed shoal-water edge (40 ft) | Diamond jig, Bucktail with teaser |
| Winter | 16 to 72 ft | midday | Sheet Harbour surveyed entrance trough (72 ft) | Heavy vertical jig |
Spring atlantic mackerel on Sheet Harbour hold shallow, usually 5 to 45 ft. By summer they slide out to 14 to 72 ft, and by winter most fish are in 18 to 72 ft. The chart's best answer is Sheet Harbour surveyed entrance trough — deep basin, 72 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a feather rig or a small vertical jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Slab Point surveyed shoal-water edge (40 ft) | Mackerel feather rig, Small silver jig |
| Summer | 14 to 72 ft | dawn & dusk | Sheet Harbour surveyed entrance trough (72 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Slab Point surveyed shoal-water edge (40 ft) | Compact silver jig, Sparse feather rig |
| Winter | 18 to 72 ft | midday | Sheet Harbour surveyed entrance trough (72 ft) | Small deep jig |
