16-acre lake in Squamish-Lillooet Regional District, British Columbia. The lake tops out around 141 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 16 acres wrapped in 0.6 miles of bank. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 3% of the surface on the model — that's where the groceries are. Squamish-Lillooet Regional District claims this one. If the bite dies, Stump Lake is 1 mi to the southwest.
Spring rainbow trout on Cat 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 40 ft. Put Main-lake point first on the milk run — a point near 35 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | open water | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (35 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (35 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (63 ft) | Jigging spoon, Tube jig (white) |
The chart marks 3 structure features on Cat Lake; the deepest is Deep basin at about 120 ft.
