Fishing Kotaselkä: what the data says
281-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. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Kotaselkä runs 280 acres with 6.9 miles of edge. With a shoreline index of 3, this water is all arms and coves — edge habitat well beyond its acreage. 59% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.
