182-acre lake in Algoma District, Ontario. The lake tops out around 59 ft. The depth data here comes from the Ontario MNRF survey of 1979, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Barr Lake draws 183 acres inside 5.9 miles of shoreline, with 5 islands in the mix. An index of 3.1 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 66% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.2 mi, about 0.7 mi across. The water lies in Algoma District. The nearest mapped water is Ed Frazer Lake, 2 mi to the east.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Main-lake point is the standout, a point at roughly 6 ft, rated prime for spring brook trout. Plan around early morning and the evening in the warm months. 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 (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (4 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (4 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 59 ft.
