12-acre lake near Gwynedd. The lake tops out around 115 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. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 12 acres wrapped in 0.6 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 6% of the water is 15 ft or less as modeled, the band where the food chain lives.
Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 25 to 60 ft; cold water stacks them in 5 to 35 ft. Top water on the chart: Break off the point, a drop-off in the 52-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.
