95-acre lake in Fraser-Fort George Regional District, British Columbia. The lake tops out around 31 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Slim Lake runs 95 acres with 5.9 miles of edge. That shoreline is heavily fingered (development index 4.4) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 87% of this chart, as modeled. Figure 2.5 mi of water from one end to the other, 0.4 mi at the beam. The water lies in Fraser-Fort George Regional District. Closest neighbour on DepthScout: Papoose Lake, 2 mi northeast of here.
In spring, rainbow trout run shallow here, mostly 5 to 20 ft. Midsummer fish sit out in 8 to 30 ft before dropping to 6 to 31 ft for winter. Spring rainbow trout concentrate at Main-lake point, a prime-rated point 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.
