70-acre lake in Capital Regional District, British Columbia. The lake tops out around 48 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Here is how the season plays out for each species, straight from the data behind the map.
Mavis Lake maps at 70 acres behind 2.5 miles of shoreline. A middling shoreline index (2.1) gives it some bays to work without being a maze. About 41% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.8 mi end to end and 0.5 mi across at its widest. It sits in Capital Regional District. Its nearest charted neighbour, Jack Lake, is 1 mi to the south.
Start shallow in spring: cutthroat trout sit in 3 to 15 ft that time of year. Warm water sends them out to 10 to 35 ft; cold water stacks them in 10 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 22 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a trolled spoon (small) or an inline spinner until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Break off the point (22 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Main-lake point (12 ft) | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Break off the point (22 ft) | Small jigging spoon, Marabou jig |
