Fishing Härkäjärvi: what the data says
1,457-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. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Härkäjärvi draws 1,928 acres inside 18 miles of shoreline. A development index of 2.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. 53% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.
