26-acre lake near Cumbria. The lake tops out around 48 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
Blelham Tarn maps at 26 acres behind 1 miles of shoreline. Nearly circular (index 1.4), so the story is the bottom, not the bank. 36% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
In spring, brown trout run shallow here, mostly 3 to 25 ft. Summer pushes them deeper, 14 to 48 ft, and winter fish settle into 5 to 35 ft. Break off the point is the standout, a drop-off at roughly 22 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.
