33-acre lake near Southesk Parish. Government of New Brunswick lake depth survey. The lake tops out around 4 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. The rest of this page walks each species through its year, using the map's own scoring.
Drawn out, this is 33 acres of water rimmed by 1.8 miles of bank. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Tip to tip the water measures near 0.5 mi with a 0.3-mi widest point. You'll find it in Northumberland County. Closest neighbour on DepthScout: North Renous Lake, 5 mi north of here.
Spring puts smallmouth bass in skinny water — 1 to 4 ft is the zone. Summer fish stay in 1 to 4 ft, and winter fish hold in 1 to 4 ft. Main-lake point is the standout, a point at roughly 2 ft, rated prime for fall 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 | 1 to 4 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 1 to 4 ft | dawn & dusk | Main-lake point (2 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 1 to 4 ft | midday & dawn | Main-lake point (2 ft) | Jerkbait, Blade bait |
| Winter | 1 to 4 ft | midday | Deep basin (4 ft) | Blade bait, Hair jig |
Early season chain pickerel use the shallows, holding in 1 to 4 ft. Even in summer they hold at 1 to 4 ft; winter keeps them in 1 to 4 ft. 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 | 1 to 4 ft | midday & dawn | Shallow bay flat (2 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 1 to 4 ft | dawn & dusk | Shallow bay flat (2 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 1 to 4 ft | midday & dawn | Shallow bay flat (2 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 1 to 4 ft | dawn | Shallow bay flat (2 ft) | Jigging spoon (through ice) |
Spring yellow perch on Halfmoon Lake hold shallow, usually 1 to 4 ft. Depth-wise the year is flat: 1 to 4 ft in summer, 1 to 4 ft once it turns cold. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. 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 4 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 1 to 4 ft | dawn | Deep basin (4 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 1 to 4 ft | midday | Deep basin (4 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 1 to 4 ft | midday & dawn | Deep basin (4 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: brook trout sit in 1 to 4 ft that time of year. They don't go far with the seasons — 1 to 4 ft covers summer, 1 to 4 ft covers winter. The spot to know is Deep basin, a deep basin in about 4 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 | 1 to 4 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 1 to 4 ft | dawn & dusk | Deep basin (4 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 4 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 1 to 4 ft | dawn | Deep basin (4 ft) | Small jigging spoon, Tungsten jig + plastic |
