27-acre lake in Nipissing District, Ontario. The lake tops out around 90 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1951, a decades-old survey (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
Found Lake maps at 27 acres behind 0.9 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. About 46% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Nipissing District. Its nearest charted neighbour, Tanamakoon Lake, is 1 mi to the southeast.
Spring lake trout on Found Lake hold shallow, usually 10 to 40 ft. By summer they slide out to 27 to 90 ft, and by winter most fish are in 20 to 80 ft. The chart's best answer is Deep basin — deep basin, 90 ft, prime for summer. Prime time lands in early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Shoreline break (1 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 27 to 90 ft | dawn | Deep basin (90 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Shoreline break (1 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (90 ft) | White tube jig, Airplane jig |
Early season splake use the shallows, holding in 5 to 25 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 10 to 45 ft. Put Shoreline break first on the milk run — a drop-off near 1 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a trolled spoon at the thermocline or a white tube jig (deep) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Shoreline break (1 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Shoreline break (1 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Shoreline break (1 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Shoreline break (1 ft) | Jigging spoon tipped with minnow head, Small white tube |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 15 to 35 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shoreline break (1 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (90 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (90 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 20 to 45 ft one. The chart's best answer is Shoreline break — drop-off, 1 ft, good for fall. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (1 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Shoreline break (1 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Shoreline break (1 ft) | Blade bait, Hair jig |
