21-acre lake near Paroisse d'Addington. Government of New Brunswick lake depth survey. The lake tops out around 17 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. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 21 acres wrapped in 0.8 miles of bank. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 98% of the surface — that's where the groceries are. Tip to tip the water measures near 0.3 mi with a 0.2-mi widest point. Northumberland County claims this one. Its nearest charted neighbour, First Lake, is 1 mi to the east.
Spring smallmouth bass on Second Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 5 to 17 ft, and by winter most fish are in 5 to 17 ft. The chart's best answer is Break off the point — drop-off, 11 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (4 ft) | Ned rig, Tube jig |
| Summer | 5 to 17 ft | dawn & dusk | Break off the point (11 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 17 ft | midday & dawn | Main-lake point (4 ft) | Jerkbait, Blade bait |
| Winter | 5 to 17 ft | midday | Break off the point (11 ft) | Blade bait, Hair jig |
In spring, chain pickerel run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 3 to 15 ft, and winter fish settle into 5 to 17 ft. Break off the point is the standout, a drop-off at roughly 11 ft, rated prime for fall chain pickerel. Time it for early morning and the evening. You won't need more than a weedless spoon + trailer or a buzzbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Break off the point (11 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Break off the point (11 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 17 ft | dawn | Break off the point (11 ft) | Jigging spoon (through ice) |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 5 to 17 ft, wintering in 5 to 17 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 16 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 17 ft | dawn | Deep basin (16 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 17 ft | midday | Deep basin (16 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 17 ft | midday & dawn | Deep basin (16 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, brook trout slide up into 2 to 15 ft. Summer is a 5 to 17 ft game here, winter a 3 to 17 ft one. Start at Deep basin.

Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |
