Fishing Iso-Kisko: what the data says
1,687-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. Here's the year, species by species, as the scoring engine sees it.
On the chart, Iso-Kisko draws 1,792 acres inside 19.2 miles of shoreline. A development index of 3.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 44% of the water is 15 ft or less, the band where the food chain lives.
