39-acre lake near Northesk Parish. Government of New Brunswick lake depth survey. The lake tops out around 8 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. What the data behind the map says about each species, season by season:
Tomogonops Lake maps at 39 acres behind 1.3 miles of shoreline. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.4 mi end to end and 0.4 mi across at its widest. It sits in Northumberland County. If the bite dies, Roger Lake is 1 mi to the north.
When the water first warms, smallmouth bass slide up into 2 to 8 ft. There's no big seasonal slide here — summer means 2 to 8 ft, winter 2 to 8 ft. Start at Main-lake point. It's a point holding about 2 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 2 to 8 ft | dawn & dusk | Break off the point (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 8 ft | midday & dawn | Main-lake point (2 ft) | Jerkbait, Blade bait |
| Winter | 2 to 8 ft | midday | Break off the point (5 ft) | Blade bait, Hair jig |
Start shallow in spring: chain pickerel sit in 2 to 8 ft that time of year. They don't go far with the seasons — 2 to 8 ft covers summer, 2 to 8 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 5 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a weedless spoon + trailer or a buzzbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | Inline spinner (silver), Small spoon (red/white) |
| Summer | 2 to 8 ft | dawn & dusk | Break off the point (5 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 2 to 8 ft | midday & dawn | Break off the point (5 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 2 to 8 ft | dawn | Break off the point (5 ft) | Jigging spoon (through ice) |
The spring pattern is a shallow one: yellow perch in 2 to 8 ft. The depth story barely changes: 2 to 8 ft through summer, 2 to 8 ft in winter. The spot to know is Deep basin, a deep basin in about 8 ft of water that rates prime for yellow perch in fall. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 8 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 8 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 8 ft | midday & dawn | Deep basin (8 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season brook trout use the shallows, holding in 1 to 8 ft. Even in summer they hold at 2 to 8 ft; winter keeps them in 1 to 8 ft. Put Deep basin first on the milk run — a deep basin near 8 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 2 to 8 ft | dawn & dusk | Deep basin (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 8 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 8 ft | dawn | Deep basin (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 8 ft.

Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout on Tomogonops Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Main-lake point is the top-rated area: a point in about 2 ft of water that rates prime for smallmouth bass in fall. Every other rated spot, per species and season, is on the map above.
For smallmouth 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.
