Fishing Trehörningssjön: what the data says
49-acre lake in Sweden. The lake tops out around 43 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. Species by species, here's what the data says the year looks like.
Trehörningssjön maps at 49 acres behind 1.4 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. About 56% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone.
