29-acre lake in Timiskaming District, Ontario. The lake tops out around 20 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 1949, a decades-old survey (an MNRF lake survey). The season-by-season read for each species follows, from the map's own numbers.
On the chart, South Coleman Lake draws 30 acres inside 1.2 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Timiskaming District. For a second option, Little Gillies Lake lies 1 mi south.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Summer fish stay in 5 to 20 ft, and winter fish hold in 4 to 20 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 5 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Break off the point (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft | dawn & dusk | Break off the point (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft | dawn & dusk | Break off the point (5 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft | dawn | Break off the point (5 ft) | Jigging spoon, Tube jig (white) |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 17 ft.
