185-acre lake in Peace River Regional District, British Columbia. The lake tops out around 77 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Dimsdale Lake runs 185 acres with 3.8 miles of edge. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. Roughly 56% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 1.5 mi of water from one end to the other, 0.5 mi at the beam. The water lies in Peace River Regional District. The nearest mapped water is Barbara Lake, 2 mi to the south.
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Break off the point is the standout, a drop-off at roughly 35 ft, rated prime for winter rainbow trout. Plan around early morning and the evening in the warm months. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
