21-acre lake in Algoma District, Ontario. The lake tops out around 39 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 1983 (a transect sounding survey). Species by species, here's what the data says the year looks like.
Rioux L. 36 maps at 22 acres behind 1 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 56% of this chart. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. It sits in Algoma District. If the bite dies, Sturgeon L. 27 is 1 mi to the west.
When the water first warms, brook trout slide up into 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. If you only fish one area, make it Break off the point: a drop-off around 11 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (11 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
