Fishing Boasjön: what the data says
22-acre lake in Sweden. The lake tops out around 39 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.
Boasjön maps at 22 acres behind 0.8 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. Roughly 39% of the water is 15 ft or less as modeled, the band where the food chain lives.
