Fishing Cossack Lake: what the data says
162-acre lake in British Columbia. The lake tops out around 48 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Cossack Lake runs 162 acres with 2.1 miles of edge. 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. Roughly 53% of the water is 15 ft or less as modeled, the band where the food chain lives.
Rainbow Trout fishing at Cossack Lake
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 22-ft range, prime in winter. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
