87-acre lake in Thunder Bay District, Ontario. The lake tops out around 20 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
On the chart, Adrian Lake draws 87 acres inside 2.3 miles of shoreline, with a single island in the mix. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. 70% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.8 mi with a 0.4-mi widest point. The water lies in Thunder Bay District. Closest neighbour on DepthScout: Stephens Lake, 2 mi northeast of here.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 20 ft, rated prime for summer 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.
