Fishing Sedan City South Lake: what the data says
108-acre lake near Sedan. Public southeast Kansas city lake with KBS surveyed bathymetric contours. The lake tops out around 22 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.
The chart traces 2.9 miles of shoreline here. That shoreline is heavily fingered (development index 2.5) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 72% of the water is 15 ft or less, the band where the food chain lives.
