Rating depth structure for smallmouth bass.
Recent public catches load as you reach this section.
35-acre lake near Paroisse d'Addington. Government of New Brunswick lake depth survey. The lake tops out around 6 ft. The depth chart comes from Government of New Brunswick DNRED bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn outline gives you 0.9 miles of bank to pick apart. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. It sits in Northumberland County. Its nearest charted neighbour, Otter Lake, is 3 mi to the east.
Early season smallmouth bass use the shallows, holding in 2 to 6 ft. Even in summer they hold at 2 to 6 ft; winter keeps them in 2 to 6 ft. The chart's best answer is Deep basin — deep basin, 6 ft, good for winter. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft chart-limited; documented 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 2 to 6 ft chart-limited; documented 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 6 ft chart-limited; documented 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 2 to 6 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (6 ft) | Blade bait, Hair jig |
Spring puts chain pickerel in skinny water — 1 to 6 ft is the zone. Summer fish stay in 1 to 6 ft, and winter fish hold in 2 to 6 ft. Deep basin is the standout, a deep basin at roughly 6 ft, rated good for winter chain pickerel. Plan around early morning and the evening in the warm months. A weedless spoon + trailer or a buzzbait covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft chart-limited; documented 2 to 10 ft | midday & dawn | open water | Inline spinner (silver), Small spoon (red/white) |
| Summer | 1 to 6 ft chart-limited; documented 3 to 15 ft | dawn & dusk | open water | Weedless spoon + trailer, Buzzbait |
| Fall | 2 to 6 ft chart-limited; documented 4 to 15 ft | midday & dawn | open water | Jerkbait along weed edges, Spinnerbait |
| Winter | 2 to 6 ft chart-limited; documented 5 to 18 ft | dawn | Deep basin (6 ft) | Jigging spoon (through ice) |
In spring, yellow perch run shallow here, mostly 2 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 2 to 6 ft. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 6 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 6 ft chart-limited; documented 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 6 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 6 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 6 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for brook trout tight to the bank in 1 to 6 ft. Through summer count on 2 to 6 ft; the winter hold is 1 to 6 ft. Start at Deep basin. It's a deep basin holding about 6 ft of water and rates good come summer. Prime time lands in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.

Halfmile Lakes is about 6 ft (2 m) deep at its deepest point. The depth chart comes from Government of New Brunswick DNRED bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout on Halfmile Lakes. 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.
Deep basin is the top-rated area: a deep basin in about 6 ft of water that rates prime for yellow perch in fall. Open the map above to see every rated spot for each species and season.
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.
