101,675-acre Trondheimsfjord. Trondheim Reach Norway saltwater fishing map with official Kartverket surveyed 50 m bathymetry, measured-only fishing spots, Institute of Marine Research fish evidence, seasonal forage guidance and public shore-access context. The main-fjord water off Trondheim and adjacent current corridors. The water tops out around 1586 ft. The depth chart comes from Norwegian Mapping Authority (Kartverket) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 101,675 acres of water rimmed by 101.8 miles of bank, with 3 islands in the mix. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 1% of the surface — that's where the groceries are. The basin spans about 22.9 mi end to end and 15.5 mi across at its widest. Closest neighbour on DepthScout: Jonsvatnet, 12 mi south of here.
The target roster combines named-water evidence where available with conservative, habitat-compatible official Norwegian coastal records. It documents occurrence context, not equal abundance, a catch rate or a promised catch. Closed targets are excluded and current rules control every trip. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

Spring atlantic cod on Trondheimsfjord - Trondheim Reach hold shallow, usually 20 to 100 ft. By summer they slide out to 45 to 180 ft, and by winter most fish are in 50 to 220 ft. The chart's best answer is Rock reef — rock pile, 2 ft, good for fall. Prime time lands in early morning. The summer box starts with a heavy metal jig or a large soft-plastic jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 100 ft | dawn | Rock reef (2 ft) | Diamond jig, Heavy bucktail |
| Summer | 45 to 180 ft | dawn | Rock reef (2 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 25 to 140 ft | dawn | Rock reef (2 ft) | Diamond jig, Bucktail with teaser |
| Winter | 50 to 220 ft | midday | Rock reef (2 ft) | Heavy vertical jig |
The spring pattern is a shallow one: saithe (coalfish) in 15 to 160 ft. As the season builds they drop to 25 to 260 ft, wintering in 45 to 320 ft. Top water on the chart: Shoreline point, a point in the 143 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a speed jig or a heavy paddletail gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 160 ft | dawn & dusk | Shoreline point (143 ft) | Slim metal jig, Paddletail |
| Summer | 25 to 260 ft | dawn & dusk | Shoreline point (143 ft) | Speed jig, Heavy paddletail |
| Fall | 20 to 220 ft | dawn & dusk | Shoreline point (143 ft) | Metal jig, Baitfish swimbait |
| Winter | 45 to 320 ft | midday | Rock reef (2 ft) | Heavy vertical jig |
Spring pollack (lyr) on Trondheimsfjord - Trondheim Reach hold shallow, usually 8 to 100 ft. By summer they slide out to 12 to 150 ft, and by winter most fish are in 35 to 220 ft. The chart's best answer is Shoreline point — point, 143 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a surface plug or a baitfish swimbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 100 ft | dawn & dusk | Rock reef (2 ft) | Sandeel-pattern lure, Soft-plastic shad |
| Summer | 12 to 150 ft | dawn & dusk | Shoreline point (143 ft) | Surface plug, Baitfish swimbait |
| Fall | 15 to 160 ft | dawn | Shoreline point (143 ft) | Metal jig, Minnow plug |
| Winter | 35 to 220 ft | midday | Rock reef (2 ft) | Slow metal jig, Weighted soft plastic |
The spring pattern is a shallow one: haddock in 35 to 220 ft. Midsummer fish sit out in 60 to 320 ft before dropping to 70 to 400 ft for winter. The spot to know is Kartverket measured flat, a feeding flat in about 221 ft of water that rates prime for haddock in fall. Plan around early morning in the warm months. Summer baits: a compact metal jig or a bottom rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 35 to 220 ft | dawn | Kartverket measured flat (221 ft) | Small bottom jig, Beaded trace |
| Summer | 60 to 320 ft | dawn | Kartverket measured flat (221 ft) | Compact metal jig, Bottom rig |
| Fall | 45 to 260 ft | midday | Kartverket measured flat (221 ft) | Small vertical jig |
| Winter | 70 to 400 ft | midday | Kartverket measured flat (221 ft) | Deep bottom jig |
When the water first warms, atlantic mackerel slide up into 5 to 45 ft. By summer they slide out to 15 to 80 ft, and by winter most fish are in 30 to 120 ft. In summer the feeding windows fall in early morning and the evening. Keep a feather rig or a small vertical jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | open water | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | open water | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | open water | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | open water | Small deep jig |
The spring pattern is a shallow one: atlantic herring in 5 to 25 ft. As the season builds they drop to 15 to 50 ft, wintering in 20 to 60 ft. Top water on the chart: Rock reef, a rock pile in the 2 ft range, good in spring. Time it for early morning and the evening. Summer baits: a herring feather rig or a small silver jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Rock reef (2 ft) | Small herring feather rig, Micro jig rig |

Trondheimsfjord - Trondheim Reach is about 1586 ft (483 m) deep at its deepest point. The depth chart comes from Norwegian Mapping Authority (Kartverket) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.

The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
Shoreline point is the top-rated area: a point in about 143 ft of water that rates prime for pollack (lyr) in summer. Scroll up to the map for the complete spot list by 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.
