Fishing Osage City Reservoir: what the data says
84-acre reservoir near Osage City. Public east-central Kansas city reservoir with KBS surveyed bathymetric contours. The lake tops out around 10 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 is how the season plays out for each species, straight from the data behind the map.
There are 2.3 miles of drawn shoreline to work. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end.
