884-acre lake near McAdam Parish. Government of New Brunswick lake depth survey. The lake tops out around 35 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What the data behind the map says about each species, season by season:
The drawn water covers 906 acres wrapped in 7.5 miles of bank. With a 1.8 development index there's bank structure worth casting at, in moderation. 67% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 2.5 mi with a 1-mi widest point. York County claims this one. If the bite dies, Sixth Lake is 2 mi to the west.
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 11 to 35.1 ft. Start at Main-lake point. It's a point holding about 9 ft of water and rates prime come fall. Prime time lands in 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 (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (16 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (9 ft) | Jerkbait, Blade bait |
| Winter | 11 to 35.1 ft | midday | Break off the point (16 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: chain pickerel in 2 to 10 ft. As the season builds they drop to 3 to 15 ft, wintering in 5 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 4 ft range, prime in spring. Time it for early morning and the evening. 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 (4 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (4 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (4 ft) | Jigging spoon (through ice) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. 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 (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring brook trout on Fifth Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 30 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring white perch on Fifth Lake hold shallow, usually 4 to 15 ft. They move out to 11 to 35.1 ft in summer and finish the year down in 11 to 35.1 ft. Put Deep basin first on the milk run — a deep basin near 30 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a small spinner rig drifted or a 1/8 oz jigging spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Shallow bay flat (4 ft) | Small jig + curly tail, Inline spinner (silver) |
