Fishing Leavenworth County State Fishing Lake: what the data says
259-acre lake near Tonganoxie. Kansas public fishing water with KDWP bathymetric map coverage and KBS surveyed contours. The lake tops out around 40 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. Species by species, here's what the data says the year looks like.
There are 4.2 miles of drawn shoreline to work. That shoreline is heavily fingered (development index 2.4) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 42% of the water is 15 ft or less, the band where the food chain lives.
