17-acre lake near Southesk Parish. Government of New Brunswick lake depth survey. The lake tops out around 15 ft. The depth chart comes from Government of New Brunswick DNRED bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
The drawn water covers 17 acres wrapped in 0.7 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. It sits in Northumberland County. Its nearest charted neighbour, Middle Peaked Mountain Lake, is 1 mi to the southeast.
Spring smallmouth bass on Upper Peaked Mountain Lake hold shallow, usually 3 to 12 ft. They move out to 5 to 15 ft in summer and finish the year down in 5 to 15 ft. Put Deep basin first on the milk run — a deep basin near 15 ft that grades good for winter. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn & dusk | open water | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 15 ft chart-limited; documented 8 to 25 ft | midday & dawn | open water | Jerkbait, Blade bait |
| Winter | 5 to 15 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (15 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 4 to 15 ft for winter. Winter chain pickerel concentrate at Deep basin, a good-rated deep basin around 15 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 | open water | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | open water | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | open water | Jerkbait along weed edges, Spinnerbait |
| Winter | 4 to 15 ft chart-limited; documented 5 to 18 ft | dawn | Deep basin (15 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 5 to 15 ft; cold water stacks them in 5 to 15 ft. Deep basin is the standout, a deep basin at roughly 15 ft, rated prime for fall 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 | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, brook trout slide up into 2 to 15 ft. There's no big seasonal slide here — summer means 5 to 15 ft, winter 2 to 15 ft. If you only fish one area, make it Deep basin: a deep basin around 15 ft that scores good 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.

Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout on Upper Peaked Mountain 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.
Deep basin is the top-rated area: a deep basin in about 15 ft of water that rates prime for yellow perch in fall. The map above holds the full rated-spot list for every species and season.
