188-acre lake in Cariboo Regional District, British Columbia. The lake tops out around 31 ft. The surface is reconstructed from 31 measured spot soundings collected in 1970; water between those measurements is interpolated. Treat the contours between those soundings as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Roger Lake runs 188 acres with 3.9 miles of edge. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. 70% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 1.4 mi with a 0.5-mi widest point. You'll find it in Cariboo Regional District. For a second option, Judy Lake lies 2 mi northeast.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Summer pushes them deeper, 8 to 30 ft, and winter fish settle into 6 to 31 ft. Deep basin is the standout, a deep basin at roughly 31 ft, rated prime for winter rainbow trout. Time it for early morning and the evening. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
