Fishing Llyn Llenyrch: what the data says
7-acre lake near Gwynedd. The lake tops out around 33 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. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 7 acres wrapped in 0.5 miles of bank. 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. 38% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water.
Brown Trout fishing at Llyn Llenyrch
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Summer pushes them deeper, 10 to 33 ft, and winter fish settle into 5 to 33 ft. The spot to know is Break off the point, a drop-off in about 15 ft of water that rates prime for brown trout in summer. Warm-month bites cluster around after dark and early morning. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
