Fishing Karjalankosken allas: what the data says
279-acre lake in Finland. The lake tops out around 66 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Karjalankosken allas runs 280 acres with 7.1 miles of edge. That shoreline is heavily fingered (development index 3) — bays, points and pockets everywhere, which multiplies the fishable edge. About 55% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.
