5-acre lake in Algoma District, Ontario. The lake tops out around 21 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 2004 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Irene Parlby L. runs 5 acres with 0.5 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. The shallow band under 15 ft claims about 94% of the surface — that's where the groceries are. You'll find it in Algoma District. For a second option, Stover Lake lies 1 mi northeast.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 6 to 21 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 19 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 (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 21 ft | dawn & dusk | Deep basin (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

| Winter | 3 to 20 ft | dawn | Deep basin (19 ft) | Small jigging spoon, Tungsten jig + plastic |
