Rating depth structure for smallmouth bass.

120-acre lake near Paroisse de Saint-Joseph. Government of New Brunswick lake depth survey. The lake tops out around 5 ft. The depth chart comes from Government of New Brunswick DNRED bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 116 acres of water rimmed by 3.5 miles of bank. An index of 2.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 1.6 mi, about 0.2 mi across. You'll find it in Madawaska County. Closest neighbour on DepthScout: Third Lake, 2 mi northwest of here.
Spring puts smallmouth bass in skinny water — 1 to 5 ft is the zone. Summer fish stay in 2 to 5 ft, and winter fish hold in 2 to 5 ft. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.
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 | 1 to 5 ft chart-limited; documented 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 2 to 5 ft chart-limited; documented 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 2 to 5 ft chart-limited; documented 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 2 to 5 ft chart-limited; documented 20 to 45 ft | midday | open water | Blade bait, Hair jig |
Early season chain pickerel use the shallows, holding in 1 to 5 ft. Even in summer they hold at 1 to 5 ft; winter keeps them in 1 to 5 ft. 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 | 1 to 5 ft chart-limited; documented 2 to 10 ft | midday & dawn | open water | Inline spinner (silver), Small spoon (red/white) |

| Winter | 1 to 5 ft chart-limited; documented 5 to 18 ft | dawn | open water | Jigging spoon (through ice) |
Spring yellow perch on Second Lake hold shallow, usually 1 to 5 ft. Depth-wise the year is flat: 2 to 5 ft in summer, 2 to 5 ft once it turns cold. 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 | 1 to 5 ft chart-limited; documented 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |

| Fall | 2 to 5 ft chart-limited; documented 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft chart-limited; documented 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: brook trout sit in 1 to 5 ft that time of year. They don't go far with the seasons — 2 to 5 ft covers summer, 1 to 5 ft covers winter. 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.

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.
