24-acre lake in Sudbury District, Ontario. The lake tops out around 43 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 24 acres of water rimmed by 1.2 miles of bank. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. 45% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 0.4 mi, about 0.2 mi across. The water lies in Sudbury District. For a second option, Little Jen L. ( L. 64) lies 0 mi east.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Break off the point, a drop-off in the 19 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.
