Fishing Thelwood Lake: what the data says
93-acre lake in British Columbia. The lake tops out around 83 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. Here's the year, species by species, as the scoring engine sees it.
Thelwood Lake maps at 93 acres behind 3.9 miles of shoreline. A development index of 2.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. About 22% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
Cutthroat Trout fishing at Thelwood Lake
Spring puts cutthroat trout in skinny water — 3 to 15 ft is the zone. Warm water sends them out to 10 to 35 ft; cold water stacks them in 10 to 40 ft. Main-lake point is the standout, a point at roughly 21 ft, rated prime for fall cutthroat trout. Plan around early morning and the evening in the warm months. A trolled spoon (small) or a inline spinner covers the summer program.
