46-acre lake near Gwynedd. The lake tops out around 10 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here's the year, species by species, as the scoring engine sees it.
Llyn y Gader maps at 46 acres behind 1.2 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout.
In spring, brown trout run shallow here, mostly 1 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 1 to 10 ft. Break off the point is the standout, a drop-off at roughly 5 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.
