Fishing Korpijärvi: what the data says
7,708-acre lake in Finland. The lake tops out around 131 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, Korpijärvi draws 7,829 acres inside 49.9 miles of shoreline. A development index of 4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 38% of the water is 15 ft or less, the band where the food chain lives.
