13-acre lake near Gordon Parish. Government of New Brunswick lake depth survey. The lake tops out around 9 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. What the data behind the map says about each species, season by season:
On the chart, Roulston Lake draws 13 acres inside 0.6 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. You'll find it in Victoria County. The nearest mapped water is Lampedo Lake, 15 mi to the south.
Spring puts smallmouth bass in skinny water — 2 to 8.9 ft is the zone. Summer fish stay in 3 to 8.9 ft, and winter fish hold in 3 to 8.9 ft. Main-lake point is the standout, a point at roughly 8 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 | 2 to 8.9 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 3 to 8.9 ft | dawn & dusk | Break off the point (4 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 3 to 8.9 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 3 to 8.9 ft | midday | Break off the point (4 ft) | Blade bait, Hair jig |
Early season chain pickerel use the shallows, holding in 2 to 8.9 ft. Even in summer they hold at 2 to 8.9 ft; winter keeps them in 2 to 8.9 ft. The chart's best answer is Shallow bay flat — weed flat, 3 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 8.9 ft | midday & dawn | Shallow bay flat (3 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 2 to 8.9 ft | dawn & dusk | Shallow bay flat (3 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 2 to 8.9 ft | midday & dawn | Shallow bay flat (3 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 2 to 8.9 ft | dawn | Shallow bay flat (3 ft) | Jigging spoon (through ice) |
Spring yellow perch on Roulston Lake hold shallow, usually 2 to 8.9 ft. Depth-wise the year is flat: 3 to 8.9 ft in summer, 3 to 8.9 ft once it turns cold. Put Shallow bay flat first on the milk run — a weed flat near 3 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 | 2 to 8.9 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 8.9 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 8.9 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 8.9 ft | midday & dawn | Deep basin (8 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: brook trout sit in 1 to 8.9 ft that time of year. They don't go far with the seasons — 3 to 8.9 ft covers summer, 1 to 8.9 ft covers winter. The spot to know is Deep basin, a deep basin in about 8 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 8.9 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 8.9 ft | dawn & dusk | Deep basin (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 8.9 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
