Fishing Kovero: what the data says
161-acre lake in Finland. The lake tops out around 98 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. What the data behind the map says about each species, season by season:
Kovero maps at 160 acres behind 4.5 miles of shoreline. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. About 54% of the surface sits shallower than 15 ft — that's the weed-and-bait zone.
