18-acre lake near Paroisse d'Addington. Government of New Brunswick lake depth survey. The lake tops out around 20 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:
Traced from the shoreline, Tongue Lake runs 18 acres with 1.2 miles of edge. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 95% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.4 mi of water from one end to the other. You'll find it in Restigouche County. The nearest mapped water is Head Lake, 1 mi to the north.
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 6 to 20 ft. Main-lake point is the standout, a point at roughly 3 ft, rated prime for spring smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (3 ft) | Ned rig, Tube jig |
| Summer | 6 to 20 ft | dawn & dusk | Main-lake point (3 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 20 ft | midday & dawn | Main-lake point (3 ft) | Jerkbait, Blade bait |
| Winter | 6 to 20 ft | midday | Deep basin (19 ft) | Blade bait, Hair jig |
Early season chain pickerel use the shallows, holding in 2 to 10 ft. Summer is a 3 to 15 ft game here, winter a 5 to 18 ft one. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Best bite is early morning and the evening. Tie on a weedless spoon + trailer or a buzzbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (2 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (2 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (2 ft) | Jigging spoon (through ice) |
Spring yellow perch on Tongue Lake hold shallow, usually 3 to 12 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. Put Deep basin first on the milk run — a deep basin near 19 ft that grades prime for fall. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (19 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (19 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 19 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 20 ft | dawn & dusk | Deep basin (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Start shallow in spring: white perch sit in 4 to 15 ft that time of year. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. The spot to know is Deep basin, a deep basin in about 19 ft of water that rates prime for white perch in summer. Warm-month bites cluster around early morning. Throw a small spinner rig drifted or a 1/8 oz jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Shallow bay flat (2 ft) | Small jig + curly tail, Inline spinner (silver) |
