Fishing Llyn Coron: what the data says
69-acre lake near Isle of Anglesey. The lake tops out around 9 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 69 acres wrapped in 1.6 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout.
Brown Trout fishing at Llyn Coron
Start shallow in spring: brown trout sit in 1 to 9 ft that time of year. The depth story barely changes: 3 to 9 ft through summer, 1 to 9 ft in winter. Top water on the chart: Break off the point, a drop-off in the 4-ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.
