211-acre lake near Southesk Parish. Government of New Brunswick lake depth survey. The lake tops out around 22 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. What the data behind the map says about each species, season by season:
The drawn water covers 213 acres wrapped in 4.4 miles of bank. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 75% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 1.4 mi end to end and 0.6 mi across at its widest. It sits in Northumberland County. If the bite dies, Mitchell Lake is 3 mi to the southeast.
Spring smallmouth bass on Logan Lake hold shallow, usually 3 to 12 ft. They move out to 7 to 22 ft in summer and finish the year down in 7 to 22 ft. Put Secondary point first on the milk run — a point near 7 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (4 ft) | Ned rig, Tube jig |
| Summer | 7 to 22 ft | dawn & dusk | Break off the point (8 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 7 to 22 ft | midday & dawn | Secondary point (7 ft) | Jerkbait, Blade bait |
| Winter | 7 to 22 ft | midday | Break off the point (8 ft) | Blade bait, Hair jig |
In spring, chain pickerel run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 3 to 15 ft before dropping to 5 to 18 ft for winter. Spring chain pickerel concentrate at Shallow bay flat, a prime-rated weed flat around 5 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a weedless spoon + trailer or a buzzbait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (5 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (5 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (5 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (5 ft) | Jigging spoon (through ice) |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 7 to 22 ft; cold water stacks them in 7 to 22 ft. Shallow bay flat is the standout, a weed flat at roughly 5 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 7 to 22 ft | dawn | Deep basin (21 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 7 to 22 ft | midday | Deep basin (21 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 7 to 22 ft | midday & dawn | Deep basin (21 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 7 to 22 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 21 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 7 to 22 ft | dawn & dusk | Deep basin (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (4 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (8 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, white perch slide up into 4 to 15 ft. By summer they slide out to 7 to 22 ft, and by winter most fish are in 7 to 22 ft. If you only fish one area, make it Deep basin: a deep basin around 21 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a small spinner rig drifted or a 1/8 oz jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Shallow bay flat (5 ft) | Small jig + curly tail, Inline spinner (silver) |

Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout, white perch on Logan Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Secondary point is the top-rated area: a point in about 7 ft of water that rates prime for smallmouth bass in fall. Scroll up to the map for the complete spot list by species and season.
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.
