Fishing Cotsworth Lake: what the data says
200-acre lake in British Columbia. The lake tops out around 26 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 is how the season plays out for each species, straight from the data behind the map.
On the chart, Cotsworth Lake draws 199 acres inside 3.9 miles of shoreline. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. 75% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
Rainbow Trout fishing at Cotsworth Lake
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 7 to 26 ft, wintering in 5 to 26 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 12 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
