22-acre lake in British Columbia. The lake tops out around 18 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here's the year, species by species, as the scoring engine sees it.
On the chart, Fifteen Mile Lake draws 22 acres inside 0.9 miles of shoreline. At index 1.4 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 92% of this chart, as modeled. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Cariboo Regional District. For a second option, Sixteen Mile Lake lies 1 mi north.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

In spring, rainbow trout run shallow here, mostly 5 to 18 ft. Summer keeps them at 5 to 18 ft, and they winter in 4 to 18 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 8 ft. Fish it in early morning and the evening and you'll meet the bite. 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.
