34-acre lake in Algoma District, Ontario. The lake tops out around 36 ft. The depth data here comes from the Ontario MNRF survey of 2022 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Brilliant Lake draws 34 acres inside 1.7 miles of shoreline, broken up by 2 islands. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 71% of this chart. Tip to tip the water measures near 0.4 mi with a 0.3-mi widest point. The water lies in Algoma District. Closest neighbour on DepthScout: Jarvis L. 9, 0 mi southwest of here.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. The spot to know is Break off the point, a drop-off in about 14 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
