717-acre lake near Fundy Rural District. Government of New Brunswick lake depth survey. The lake tops out around 75 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.
The drawn water covers 763 acres wrapped in 15.3 miles of bank. A development index of 4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Littoral water — the productive band under ~15 ft — makes up 37% of this chart. Call it 3.2 mi long by 1 mi wide at the broadest reach. It sits in Kings County. Scott Lake sits 1 mi north — 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 20 to 45 ft. If you only fish one area, make it Main-lake point: a point around 9 ft that scores prime in fall. 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 (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (25 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (9 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (25 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 2 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 (2 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (2 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Back-bay flat (16 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Back-bay flat (16 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: Break off the point, a drop-off in the 25 ft range, prime in summer. 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 (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (25 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (25 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Back-bay flat (16 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring brook trout on Seven Mile Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Break off the point — drop-off, 25 ft, prime for summer. Prime time lands in 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 | Break off the point (25 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 | Back-bay flat (16 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring white perch on Seven Mile Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 15 to 40 ft, and by winter most fish are in 20 to 50 ft. The chart's best answer is Shallow feeding flat — feeding flat, 20 ft, prime for summer. Prime time lands in 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 | Back-bay flat (16 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Shallow feeding flat (20 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 15 to 45 ft | midday | Break off the point (25 ft) | Jigging spoon (small), Blade bait |
| Winter | 20 to 50 ft | dusk | Break off the point (25 ft) | Small rattle spoon, Tungsten + spikes |
Early season landlocked salmon use the shallows, holding in 1 to 15 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 10 to 40 ft. Put Break off the point first on the milk run — a drop-off near 25 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + streamer down deep or a thin spoon on lead core and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (25 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Break off the point (25 ft) | Small jigging spoon, Swedish pimple + smelt |

Anglers target smallmouth bass, chain pickerel, yellow perch, brook trout, white perch, landlocked salmon on Seven Mile 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.
Main-lake point is the top-rated area: a point in about 9 ft of water that rates prime for smallmouth bass in fall. The map above holds the full rated-spot list for every 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.
