75-acre lake in Haliburton County, Ontario. The lake tops out around 50 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
On the chart, Niger Lake draws 75 acres inside 3.5 miles of shoreline — one island included. The 2.9 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 53% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.9 mi end to end and 0.5 mi across at its widest. You'll find it in Haliburton County. Closest neighbour on DepthScout: Bright Lake, 1 mi south of here.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Spring brook trout concentrate at Main-lake point, a prime-rated point around 5 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (8 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (8 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring pumpkinseed on Niger Lake hold shallow, usually 1 to 8 ft. They move out to 2 to 10 ft in summer and finish the year down in 6 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 5 ft that grades prime for spring. The feeding windows run the evening and early morning. The summer box starts with a micro tube or a sponge spider (fly).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (5 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
