Rating depth structure for rainbow trout.
Shared by DepthScout anglers. Exact spots stay private, always.
7-acre lake in Capital Regional District, British Columbia. The lake tops out around 39 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 drawn water covers 7 acres wrapped in 0.5 miles of bank. At index 1.3 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 38% of this chart, as modeled. Capital Regional District claims this one. Its nearest charted neighbour, Young Lake, is 1 mi to the north.
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. They move out to 3 to 12 ft in summer and finish the year down in 10 to 25 ft. If you only fish one area, make it Deep basin: a deep basin around 33 ft that scores good in winter. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | open water | |
| Summer | 3 to 12 ft | night & dusk | open water | |
| Fall | 5 to 15 ft | dusk | open water | |
| Winter | 10 to 25 ft | midday | Deep basin (33 ft) |
Spring rainbow trout on Poirier Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 39 ft. Put Break off the point first on the milk run — a drop-off near 18 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
