6-acre lake in Timiskaming District, Ontario. The lake tops out around 23 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here's the year, species by species, as the scoring engine sees it.
On the chart, Tyrrell L. 47 draws 7 acres inside 0.6 miles of shoreline. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. Littoral water — the productive band under ~15 ft — makes up 62% of this chart, as modeled. The water lies in Timiskaming District. For a second option, Tyrrell L. 21 lies 0 mi south.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 7 to 23 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 20 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
