16-acre lake in British Columbia. The lake tops out around 80 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, Forum Lake runs 16 acres with 0.6 miles of edge. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 12% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
Early season cutthroat trout use the shallows, holding in 3 to 15 ft. Summer is a 10 to 35 ft game here, winter a 10 to 40 ft one. The chart's best answer is Shoreline break — drop-off, 36 ft, prime for summer. Best bite is early morning and the evening. Tie on a trolled spoon (small) or a inline spinner and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 15 ft | dawn & dusk | open water | Inline spinner (silver/gold), Small spoon |
| Summer | 10 to 35 ft | dawn & dusk | Shoreline break (36 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | open water | Casting spoon, Inline spinner |
| Winter | 10 to 40 ft | dawn | Shoreline break (36 ft) | Small jigging spoon, Marabou jig |
