95-acre lake in Nipissing District, Ontario. The lake tops out around 72 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here is how the season plays out for each species, straight from the data behind the map.
Gauvreau Lake maps at 94 acres behind 2.2 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. About 25% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.8 mi end to end and 0.4 mi across at its widest. It sits in Nipissing District. Perron Lake sits 1 mi southwest — the closest neighbouring chart.
Spring brook trout on Gauvreau 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, 32 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 | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (32 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (18 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 22 to 72 ft, then a winter hold in 18 to 72 ft. Start at Deep basin. It's a deep basin holding about 61 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 22 to 72 ft | dawn | Deep basin (61 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (18 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 72 ft | dawn | Deep basin (61 ft) | White tube jig, Airplane jig |
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: Shallow bay flat, a weed flat in the 6 ft range, prime in spring. 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 (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (32 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (32 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (32 ft) | Tungsten jig + spikes, Rattle spoon (small) |
