121-acre lake in Nipissing District, Ontario. The lake tops out around 39 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 123 acres wrapped in 3.5 miles of bank. The 2.3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. 59% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 1.1 mi end to end and 0.5 mi across at its widest. It sits in Nipissing District. White Partridge Lake sits 2 mi west — the closest neighbouring chart.
Spring brook trout on North Branch 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, 18 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 (10 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (18 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (10 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (18 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 39 ft. Through summer count on 12 to 39 ft; the winter hold is 10 to 39 ft. Start at Deep basin. It's a deep basin holding about 33 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 39 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 12 to 39 ft | dawn | Deep basin (33 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 8 to 39 ft | dusk & dawn | Main-lake point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 10 to 39 ft | dawn | Deep basin (33 ft) | White tube jig, Airplane jig |
When the water first warms, brown bullhead slide up into 2 to 8 ft. By summer they slide out to 3 to 12 ft, and by winter most fish are in 10 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 5 ft that scores prime in spring. In summer the feeding windows fall in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (5 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (5 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (5 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (33 ft) |
