44-acre lake in Mount Waddington Regional District, British Columbia. The lake tops out around 20 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 44 acres, worked by 1.6 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 87% of the surface on the model — that's where the groceries are. Figure 0.6 mi of water from one end to the other, 0.2 mi at the beam. Mount Waddington Regional District claims this one. If the bite dies, Thiemer Lake is 1 mi to the southeast.
In spring, cutthroat trout run shallow here, mostly 3 to 15 ft. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 5 to 20 ft. Break off the point is the standout, a drop-off at roughly 9 ft, rated prime for summer cutthroat trout. Time it for early morning and the evening. You won't need more than a trolled spoon (small) or an inline spinner most summer days.
