386-acre lake near Lorne Parish. Government of New Brunswick lake depth survey. The lake tops out around 36 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 season-by-season read for each species follows, from the map's own numbers.
Island Lake maps at 402 acres behind 8.2 miles of shoreline. A development index of 2.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. 93% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 1.7 mi long by 0.9 mi wide at the broadest reach. It sits in Victoria County. Long Lake sits 4 mi northwest — the closest neighbouring chart.
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 11 to 36 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in winter. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (1 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (10 ft) | Jerkbait, Blade bait |
| Winter | 11 to 36 ft | midday | Break off the point (10 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: chain pickerel in 2 to 10 ft. Midsummer fish sit out in 3 to 15 ft before dropping to 5 to 18 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 1 ft of water that rates prime for chain pickerel in spring. Plan around early morning and the evening in the warm months. Summer baits: a weedless spoon + trailer or a buzzbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (1 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Break off the point (10 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Break off the point (10 ft) | Jigging spoon (through ice) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Deep basin, a deep basin in the 34 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (34 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (34 ft) | Tungsten jig + spikes, Rattle spoon (small) |
